How to connect a hard drive to a Pentium 3. How to properly connect a second hard drive to a computer

Twitter

Hello, friends. Sooner or later, disk space runs out. We constantly fill our devices with data and one day we find out that there is no more space on our disk. And I want it to always be there. Today I’ll tell you how you can quickly solve this problem yourself. In today's article we will connect the hard drive to the computer ourselves.

So, friends, you have discovered that you have a problem, but don’t worry, connecting the HDD is actually simple. IN regular computer install from one to six hard drives. You can turn them into a place to store files, or install another operating system. For example, you have Windows 10 on one disk, and Windows friend 7. When necessary, you boot from “seven”, and when not, from “ten” - you can do that. And you can do RAID arrays if necessary.

We connect a 3.5 hard drive from a laptop to a computer via a USB adapter

The easiest and most hassle-free option is to buy an external portable hard drive. This drive is connected via a USB connector and used as a large flash drive. The advantage of this solution is that you can store a lot of things on it? It connects easily to your computer, is compact and easy to carry. There are also disadvantages:

the presence of a cord that must be connected all the time;
speed read-write lower than that of a disk connected in the usual way;
special sensitivity to shocks and falls.

What does this have to do with a laptop disk? Inside this building is the most regular hard laptop disk. And if you have such a used laptop disk, you can make it portable yourself. The most important part is the adapter. You can buy an adapter in a store, taking the disk with you, and the seller will select an adapter for you, and perhaps even a beautiful case. Putting everything together we get a portable disk:

It can now be connected to USB port. Or this option, without an adapter, just a connector screwed to the case, into which the hard drive is then inserted. The body itself can be secured in a basket system unit for screws:

This option is suitable for connecting an HDD without an adapter, inside the system unit. Read on.

Connecting a HDD without an adapter at home

You can easily connect the same 3.5 hard drive yourself. You will need an additional SATA cable for the hard drive and possibly an additional power plug (if there are not enough connectors on the power supply). On sale there are the following cable options where everything is in one:

We open the system unit after disconnecting all the wires from it, and unscrew the screws:

...remove the cover,

Connect the data cable to motherboard…

...and the hard drive along with the power connector:

It is highly desirable that the 3.5 disk does not hang on the wires. If possible, it is better to secure it in a stationary state to avoid vibrations and shocks.

Then, we find a suitable place for it and secure it, if possible, with standard mounting screws in the basket, or at worst with plumbing tape, so that our disk is firmly and motionlessly fixed. We put the cover of the system unit in place.

How to connect a second, additional hard drive to a computer via a SATA connector

if you have standard hard drive from your computer, you can just as easily connect it as a second drive. We do everything according to the same scheme. First, we secure the new disk with standard screws on both sides in the disk basket so that there is no vibration:

Then we connect the cable and the power connector. The disk is connected.

Connecting an IDE hard drive to the motherboard and SATA connector

If your computer's motherboard has connectors for connecting hard IDE drive, you can try connecting such a drive. For a long time, all computers worked on the IDE interface, something like this until 2005. A disk with such an interface looks like this:

The connection socket looks like this:

Sometimes the connectors are multi-colored. And the cable for connecting to the motherboard looks like this:

The blue block connects to the motherboard, the black (topmost) to the hard drive, and the white to the DVD drive.

Eat important point using IDE disk ov. If you are going to use such a disk, you need to correctly switch the jumper to the position Master or Slave. This option tells the system what role this disk will play. Master— this disk is considered the main one, and loading will take place from it. Slave— secondary disk.

U different manufacturers own pinout of jumpers. The decoding of the switching modes is always indicated on the disk case:

By setting the jumpers to a certain position, we indicate the priorities - which disk is the main one. Previously, when there were several such disks, it took a lot of time to switch them. The SATA interface does not have these disadvantages. The IDE interface has long been outdated and is no longer used modern devices. However, you can connect your existing IDE drive to the SATA socket on the motherboard using a special adapter. You need to connect the adapter to the IDE drive:

...and a SATA cable and power cable to the motherboard and power supply. In this way you can increase disk space by some albeit small (by modern standards) amount. Everything is more than a flash drive!

If you bought new hard disk, it must be initialized before use, otherwise Windows will not see it, even if it is connected correctly. This is done using special programs type Acronis Disk Director 12. First, install the disk in the system unit, connect, load Acronis Disk Director:

At first you will not see the new connected disk under Windows. However, if in your Windows versions If the “Disk Management” snap-in is available, you can try to initialize the connected disk through this snap-in. In the photo, we first went to “Computer Management”, then to “Disk Management”.

However, I always use Acronis; it is guaranteed to see all disks connected to the computer.

You need to select the desired disk, right click bring up the menu with your mouse, select “Initialize disk”, and then at the very top click “Apply pending operations”:

After initialization, we create a partition or partitions on the disk, formatting them in the NTFS file system. At this point, the operation of connecting the disk to the computer can be considered completely completed. We connected it physically and programmatically. After these steps, the disks can be used for their intended purpose - installing an operating system or making volumes out of them to store your data.

If you decide to install another operating system on a new drive, then after installation, when you boot your computer, you will need to select the drive on which you installed it. This is done through the BIOS. To enter the BIOS, first press the key DEL, and then select the desired disk:

I repeat, you need to select from the list that appears the disk that you need. You can then change the download at any time. In general, you can connect a hard drive yourself very easily, try everything and you will definitely succeed.

How to connect sata hdd to ide
Just in case, let's immediately point out the external differences. IDE - also known as ATA - Advanced Technology Attachment (advanced connection technology) and later - PATA - a standard interface for connecting hard drives and drives to a PC, was popular in the 90s and early 2000s. It is a wide, 40-pin cable. SATA (Serial ATA) - the standard that later replaced it, became popular in the mid-2000s and is still relevant today, much smaller - 7 contacts versus 40.
With the passage of time and the evolution of progress in the market, new, high-speed interfaces are replacing the old ones, and the problem of compatibility inevitably arises - is it worth throwing away an HDD that is incompatible by default? modern system? Or vice versa - if the outdated motherboard does not have a SATA controller ( this interface is a standard on this moment), and a well-worn forty-gigauge screw with an 80-pin cable has given up a long life - you will be surprised to find that you can no longer find such a rarity in the nearest computer store, and the machine should still work... Just how to make it work with a relatively new sata hdd to ide? We will try to answer these questions.
How to connect SATA HDD to IDE?
The solution to both problems lies on the surface - a HDD with an old interface is very difficult to find in a store, but here is a controller that makes it easy to make almost any new hard drive work on the old system- quite! As a rule, this is a small chip, on one side of which there is an output for an IDE cable (the 40-pin wire itself is plugged into the corresponding output on the motherboard and into the controller), and on the other - SATA (connects directly to the hard drive) and 4-pin power supply ( comes from the PC power supply).
Nuances and disadvantages
It is worth considering that if you have a well-worn computer, then with a high degree of probability its power supply is old - and hard drive SATA power supply in some cases differs from that of IDE (i.e. not MOLEX) - you need either new block, or another adapter (it’s not difficult to find one, but its price is pretty cheap).

There is also one obvious disadvantage this approach– if the hard drive is designed for SATA and takes advantage of this interface, then when connected via the old bus, the speed will be noticeably limited: even the very first revision of Serial ATA gives in theory from 150 MB/s versus 133 for IDE, and the difference in throughput is several times not in favor outdated port. Otherwise, you can even connect an SSD to an old system, but the higher the speed indicators of the connected media, the more noticeable the loss in speed will be.
Also, do not forget that old hardware often has an outdated operating system, which may not support partitions larger than 2 TB or even file NTFS system. For majority decision similar problems you will need a program to work with HDD partitions– you will need to properly partition and format the volumes in order for the OS to see them and install on them. In some cases (for example, in the case of excessively large 32x volumes bit systems and Windows XP) there is nothing to be done, and you will have to put up with the limitation.
How to connect IDE HDD to SATA?

The story is approximately the same in the opposite case, with the only difference that a problem with power supply for the media will be less likely and there will be no speed restrictions, only you need to keep in mind that an IDE hard drive connected to a modern PC may become tasks “ bottleneck” – even new HDDs with high spindle speed and SATA interface latest version performance is far from exorbitant - the gain from the same SSD is more than noticeable, therefore, at a minimum, we do not recommend installing an operating system on an outdated screw. Also keep in mind that IDE devices, unlike SATA, do not support “hot swapping” - i.e. they cannot be connected or disconnected while the computer is running - there is a high probability of failure of either the device itself or the controller that is responsible for its operation!
ISA/PCI/PCIexpress controllers
There are also expansion cards for PCI connector– if there is one on the board, then you can organize the connection of drives using it. Such boards may have 2 or more SATA connectors and one IDE - do not forget that it is possible to connect two devices to it simultaneously. The disadvantage of this approach is that by default the OS or its installer may not support it (the PCI controller), and this will lead to additional headaches with creating bootable media with drivers. Plus, controllers on some chips are poorly compatible with certain systems– either they will not be detected at all, or it will be impossible to select such a thing in the BIOS HDD bootable(basically, such PCi boards have their own “mini-Bios” and their own disk tree), or the computer with it will refuse to turn on at all. Often these problems cannot be solved unless updating the motherboard firmware can help.

There is also one more nuance - the PCI standard has had many revisions, and the old ones support much lower data transfer rates, which can also impose some restrictions. On very ancient ones personal computers, which appeared before the widespread use of PCI, have an ISA bus at their disposal - there are IDE controllers for it. But due to technical limitations, when connecting a drive with more or less normal characteristics to them, the outdated bus will become a serious limitation, and with the help complex circuit(ISA IDE->SATA) you can connect almost any hard drive. For modern motherboards without a PCI connector (and there are more and more of them), there are combined solutions for PCIexress/miniPCiexpress, which have both IDE and SATA. There are far fewer problems with their support, although the speed advantage of the new express standard over the old PCI will not significantly increase the performance of the drive (if we are talking about IDE).

A hard drive is a computer's storage unit. Bytes of information are recorded in it and do not disappear even when the power is turned off, which cannot be said about RAM. Having an HDD (hard drive) is mandatory for using any PC, but the problem is that the laptop does not have obvious connectors for connecting it, so we will look into the hidden part of it.

First of all, you should find out what kind of HDD you have (if you want to connect an existing one), since they also differ in form factor and size. IN desktop computers 3.5 hard drives are used, which have a height of 25mm, and laptops use 2.5 drives with a height of 9.5mm or, in older models, 12.5mm.

Accordingly, to find out whether it is possible to connect a hard drive to a laptop in a standard way, that is, when replacing the main HDD, you need to find out what kind of hard drive you have, and based on this, the necessary actions will be taken.

Initially, we will look at how to connect a disk to a laptop with its replacement, then another situation: how to connect second hard disk to a laptop with different interfaces.

Replacing HDD on a laptop

If in a stationary device, in order to remove the hard drive, you need to unscrew the cover, remove the connection cables and unscrew the screws at the fastening points, then here the situation is a little different. Next we will consider simple replacement HDD, provided that you have a 2.5 hard drive.

Turn the laptop over and you will see a large plastic cover with bolts, sometimes there are several of them, then remove each one until you find the disk, usually under the last part;
Unscrew the screws holding the device; sometimes special grooves are used instead;
Pull the disk back, grasping the side where the contacts connect;
Lifting up you can get the HDD;
Install another hard drive in the same way.

An elementary situation is considered, which involves replacing identical devices, how to connect a 3.5 SATA HDD to a laptop or install additional devices.

How to connect a SATA hard drive to a laptop?

Situations with different types devices. First, let's look at the option of connecting SATA hard drives using an adapter. This method will allow you to connect the hard drive to the laptop via USB connector, which is very convenient, but slightly slows down the system’s response speed when working in it.

Be sure to make sure that you have a SATA interface, as older models used IDE.

To perform this procedure, you need to purchase an adapter from SATA to USB; it can be found everywhere. affordable price. Just like the SATA connection, 2 connectors are used: one is data transfer or control, the other is power supply, which is shorter in length - this information flow, exactly the same with the adapter. See photo.

There are 2 wires from the adapter, one is responsible for power, you need to connect it to the network, the other has USB output, it should be connected to a laptop, preferably to USB 3.0. Thus, regardless of the size, you will have a makeshift external HDD.

There is another connection method, which involves using a box. This box is equipped with a built-in SATA or IDE to USB adapter, completely turning the internal drive into an external one. The advantage of using this method will be protection from external damage to the device. This box can also be used (if SATA 2.5) to connect a second internal disk.

To connect a second internal drive, you will have to sacrifice the drive and replace it with a pocket for an SSD or HDD. Still, in 2016, using a CD-ROM is not relevant for most cases. This kind of pocket does not require great effort in connection: you need to remove the drive and insert the pocket directly in its place. Connecting a CD-ROM and HDD is no different, so adapters are not needed. Of course, you will have to disassemble the laptop a little. Such a pocket costs from 200-300 UAH.

What should I do if my hard drive is not showing up?

An unpleasant situation happens and after connecting, even if it is correct, the HDD still does not appear or does not work. Manipulations to solve the problem are carried out in the system. It takes a little effort to fix the glitch, since Windows must install the hard drive itself.

If the box, adapter or hard drive is not standard, then you may need to manually install the drivers. First you need to find out if this is true:

Click Start and right-click “Computer”, then “Properties”;
Now click on the “Device Manager” link;
In the “Disk Devices” section there should be an item with the name of your disk and there should not be a yellow exclamation mark icon on it.

If everything is in order, then proceed further, but if there is no such item or it is marked as problematic, then the problem is in the driver. You can right-click and select “Update drivers...”, if that doesn’t help, then you can find them on the manufacturer’s website. There should be no problems with installation.

Another case is when the drive letter is not determined, then you should:

Go to “Control Panel” from Start;
Click on the “Administration” tile;

Now select "Computer Management";

In the left menu, find “Disk Management”;

You should be able to see second HDD, to display it initially must change the letter. This is done via right click;
If it doesn’t help, format it by right-clicking and the corresponding item. File system must match, usually NTFS or FAT32.

That's all, we were able to connect the hard drive to different conditions and configure it for further use.

The hard drive is solid state drive, which is so called in contrast to floppy - floppy disk, which has not been used by users for a long time. The operation of connecting a hard drive is not so complicated and in many cases the user can do everything independently, without contacting computer specialists.

In what cases do you have to connect hard drives?

When upgrading, you replace the old drive with a more powerful and larger one.
For expansion disk memory. For example, to place computer games and some applications on a separate hard drive.
During repair - replacing a failed drive with a functional one.
To read large amounts of previously recorded information.

Basic provisions

If a system unit with an IDE interface has more than one hard drive, then one of them on the bus is designated as the main one, and the second as the auxiliary one. The first one is called Master, and the other one is called Slave. Such a division is required so that when loading the operating system after turning on, the computer knows exactly which disk is the boot one.

In all cases, you can set the boot sequence from drives using the BIOS settings. And in IDE this is done by installing jumpers on the disk enclosures according to the diagram shown on the enclosure.

By type of interface, hard drives differ between IDE – the old model and SATA – in all new computers. If you have old model system unit, and you are going to connect a new hard drive with SATA interface, you will need to purchase a special adapter.

Junk

It happens that you pick up this old thing and can’t figure out what to connect and where. Old IDE interface(1986) is put on a parallel train of wires. Usually there are either 2 or 4 connectors on the motherboard. Always an even number, because the Master/Slave rule works. Settings can be specified using jumpers (example):

Master – the presence of a jumper between the leftmost contacts (7 and 8) of the control connector.
Slave – absence of any jumpers.

The specified configuration may vary depending on the manufacturer, as well as the set valid functions, specified by the connector. The IDE interface made it possible to conveniently connect a hard drive and a CD drive to the computer at the same time. This was enough for most users. The disadvantage of the parallel interface was the low transfer speed. In another way, IDE is referred to among professionals as parallel ATA or ATA-1. The transfer speed of such devices does not exceed 133 Mbit/s (for ATA-7). With the introduction of the interface in 2003 Serial SATA the aging information transfer protocol began to be called parallel PATA.

The name ATA-1 was assigned to the IDE interface in 1994 when it was recognized by the ANSI organization. Formally, it was an extension of the 16-bit ISA bus (predecessor of PCI). It is curious that in modern world there is a trend of using video card interfaces to create connection ports hard drive ov. This was followed by accelerated ATA-2 and packet ATAPI. The IDE interface has not been officially supported since December 2013. Connecting such a hard drive to a new motherboard is only possible with an expansion card.

Using such devices, you can perform the exact opposite function: install previous generation hard drives on new motherboards. So, for example, on the old A7N8X-X there are only two IDE ports, but there are 5 PCI 2.2 slots for expansion cards. The universal adapter is just right for this case. And you can install a modern hard drive up to SATA3, but its operating speed will, of course, be several times lower than the maximum.

Hard drives under standard interfaces IDEs are probably mostly out of order by now. And there are not so many of them left in the world. It remains to add to this that the configuration of ATA devices can be changed using jumpers, and the explanatory drawing is located directly on the device body. Unscrupulous suppliers sometimes keep jumpers for themselves, and not every configuration in this case can be carried out by the user. There are usually not enough jumpers.

Today there is a new trend: traditional PCI cards, which were supplanted for some time by PCI Express cards, are reappearing on motherboards. This means that “old stuff” can now be connected to a modern system unit using an adapter.

SATA drives

Experts generally distinguish three generations of SATA. The gradation is based on the speed of information transfer:

SATA – 1.5 Gbit/s.
SATA2 – 3 Gbit/s.
SATA3 – 6 Gbit/s.

A standard SATA drive has two connectors, one of which is used for power supply, and the second serves as a data transfer cable. It is not recommended to swap hard drives by connecting them to different SATA ports. The plugs have keys that prevent the connector from being connected incorrectly.

Sometimes the hard drive may show helpful information, understandable to any advanced user. But sometimes the designation tends to be so ornate that only a true professional can comprehend it. As, for example, in this case.

There is information about the brand, serial number, technical data and even disk capacity measures. But its interface remains unknown. This is important when choosing hardware for a computer with disabilities. If the disk had a SATA3 interface, then it is useless to install one in an old system unit. There are many other similar examples. Let's say in advance that this drive has a SATA 2.6 interface. Consequently, its information exchange rate limit is 3 Mbit/s.

If information about the HDD interface type is available

How to distinguish? First, you can look at the body. Here is an image of an old disk that supports two speeds, therefore, it is a SATA2 device.

When removed from the system unit, it was equipped with a jumper that reduced the speed.

The jumper was immediately removed, therefore, the device will now function twice as fast. On the SATA 2.0 bus of the GA-H61M-D2-B3 motherboard.

This once again suggests that it is not enough to buy a system unit; you also need to study its entire device in general and hard drives in particular. The drives inside were paired using a special hanging frame.

This achieves better maintainability of the structure. Both hard drives were quickly removed from the case. As an alternative, a bay installation option is used, where the housing is secured with screws on both sides, and two side covers must be removed for dismantling. Which is not very convenient, considering that each of them usually jams. It is rare to find system unit cases where the sidewalls are removed using simple methods.

If HDD interface data is missing

Sometimes the hard drive may not have data transfer speed information. In this case, you can, of course, stock up on AIDA, but it’s even easier to look up the information on the Internet. By price or appearance The brand of the drive is determined by the case.

Let's say we have WD5000AAJS in our hands. Only one thing is known - at lunchtime he will be a hundred years old. Therefore, you need to familiarize yourself with historical information on the Internet. Since models are constantly updated, you need to enter the code followed by a dash - 00YFA0. The search engine quickly gave the answer, and now there is every reason to say that throughput channel is 3 Gbit/s (SATA 2.5 generation).

We have already discussed above how to connect such equipment to an outdated motherboard that does not have a SATA interface. So let's move on to new products.

Connecting SATA to exSATA bus

When engineers approached the problem of magnification SATA speeds up to 12 Gbit/s and higher, it turned out that this was not economically viable. Energy efficiency drops sharply while prices rise. Someone noticed that the tire graphic cards PCI Express works without problems with high speeds, and then it was decided to make some kind of hybrid between it and the outgoing SATA. To do this, the connector was divided into two parts:

Specific. Small port on the side.
Standard. Two ports for SATA0 connection.

The figure shows a dual exSATA port. This can include 4 hard drives with a SATA interface, or 2 exSATA, or 1 exSATA and 2 SATA. Below is an example of including two SATA drives to one exSATA port.

Due to its large size, covering three exSATA slots at once, the plug is called a hub among professionals. You need to start with BIOS checks. It turned out that some motherboards can turn off SATA support, completely switching to Express, which supports speeds of up to 16 Gbps.

At the same time, you can look at the BIOS capabilities regarding RAID arrays. Let us remember that in the latter case, several hard drives can duplicate their information for reliability, or turn on alternately, which significantly increases the speed of operation. The size of the article does not allow us to speak in more detail on this topic.

The selected AHCI mode is the default mode for most systems. It provides maximum compatibility with older equipment in a completely transparent manner for the user. To safely hot-plug drives, it is recommended to set the appropriate option in the BIOS settings.

When installing a new operating system, the sequence for connecting bootable media is specified. The hard drive is not put in first place. Instead, leadership is given to a flash drive or DVD drive.

Before connecting

How to connect an IDE hard drive

On the motherboard, the IDE connector is visible from afar. You can recognize it by its characteristic slot with many contacts and a key located approximately in the center of the block.

A splitter cable is usually hung on each port, so that a master and a servant are on the channel at the same time.

Before connecting a drive, you need to correctly configure the jumpers on its case - Slave or Master. There will definitely be a diagram on the case on how to do this.

For drives from different manufacturers, the order in which jumpers are inserted will be unique (they seem to be competing in this). The disk must be a bus master, otherwise the operating system cannot be started from it (No IDE Master detected). Therefore, it is necessary to set the slave jumper on the CD drive.

After setting the jumpers, insert the hard drive into a suitable cage and secure it with four screws on both sides. Connect the single data cable connector to the corresponding header on the motherboard. Connect the power cables. The order doesn't matter here.

Now you can close the system unit covers and connect the computer. The system itself should detect new connections and configure everything. The user will only have to confirm operations in the Add New Equipment Wizard.

If the system is confused about where the Master is and where the Slave is, then it is necessary to make assignments in the BIOS. Immediately after turning on the power, press the F2 or Del key repeatedly (in different ways) to open BIOS installation. Find the order description interface boot devices, set the parameters. The first is the CD drive from which the system is installed. Save the settings using the F10 key. After this, the operating system will begin loading.

How to connect a SATA hard drive to an old motherboard

To connect a SATA hard drive, use an adapter for PCI buses. It may have one or another number of ports; accordingly, several hard drives are installed.

Insert the card into the slot, connect the hard drive, place it in the bay and secure it with screws on both sides - two or four screws in total. It is advisable to choose the location of the modules inside the system unit in such a way that, if possible, there is enough space between them free space to provide ventilation. Otherwise, if the computer overheats, it will automatically turn off.

Now connect the power cable to the hard drive. If the power supply is an old model for IDE, you will need an adapter to connect SATA. Now you can connect the data cable to the hard drive. After the system boots, you should install the driver from the included DVD, and new drive will become visible through Explorer.

Sometimes there is no other drive other than SATA. And then you need to install Windows again via a PCI adapter. The bootloader will not see the drive, but will give you the opportunity to find it manually. This is where you will need to find the required driver for the current operating system on the DVD. The installer will then notice the disk and you can create partitions for the new operating system. This is absolutely accurate, because the authors installed the “seven” in this way on an old system unit.

USB 3.0 external hard drive

The serial interface has become so fast (up to 5 Gbps) that external hard drives using USB 3.0 are now available. The motherboard usually has 20-pin sockets, in addition, some of the ports are located on the rear wall. But if you plan to install an operating system on the hard drive, it makes sense to place it inside the system unit. Adapters from 20-pin to microUSB 3.0 typeB are usually not found, but you can use intermediate adapters for docking.

Hello dear readers. Today I will touch on the error in which at the beginning windows loading the inscription appears

This error is due to an incorrect hard drive connection. Therefore, based on this, I will tell you how to properly connect a SATA/IDE hard drive.

Correct connection of the hard drive.

The most common interfaces of modern hard drives are SATA, and for a slightly outdated interface IDE. SATA is more productive than IDE.

This is what IDE connectors look like...

For each IDE controller you can connect two devices. This can be an HDD and a CD/DVD drive, or two HDDs, or two CD/DVD drives. Typically, controllers are designated as IDE0 and IDE1.
When connecting two drives, you need to assign priorities to them. In other words, you need to tell the system main disk- master and slave disk. ( sometimes they are designated as device 0 - master and device 1 - slave). How are these priorities assigned? Using a jumper, jumper (in English jumper).

On the sticker of the HDD drive, as a rule, manufacturers indicate how to set the jumper so that the drive becomes the master or slave.
Devices are connected to these connectors via an IDE cable. The cables come in 40-pin and 80-pin. According to the connection mode, the cables are also Y-shaped. They operate in cable select mode. Such cables have three connectors - two at the end of the cable ( first master, second slave) and one in the middle. The central connector is connected to system board, and the extreme connectors to the devices.

Moreover, the outermost connectors automatically assign master priority to one device and slave to the other.
operating system installed on the main drive. If the disk on which the OS is installed is connected to the slave connector, the OS will not load.

SATA interface

SATA connectors on the motherboard look like this.

Devices are connected to the SATA connector using a cord with plugs. The plugs have special “keys”, guides in the shape of the letter “L” that prevent them from being connected incorrectly. Unlike IDE, you can connect only one device to one SATA connector. The connectors are designated as SATA0 - the first, SATA1 - the second, SATA2 - the third, etc. Thus, SATA distributes priorities between hard drives. In the BIOS, each connector can be manually assigned a priority. To do this, go to the Boot Sequence or Boot Device Priority section. This may be needed in cases where the automatic priority is not set correctly.
Now let's move on to solving the error problem no idea master h.d.d. detected press f1 to resume.

Error: no ide master h.d.d detected: press f1 to resume

This error appears when incorrect connection HDD. This error indicates that the system does not have a HDD connected to the master connector. This means that the HDD operates in SLAVE mode, i.e. connected to the SLAVE connector. It is necessary that at least one HDD operates in master- main. This problem can be solved by simply switching the HDD to an adjacent one. SATA connector, or if you have an ATA cable, simply move the jumper to master. That's all I guess.
