Determining the device
The first step is to determine exactly how the computer does not see your usb drive. This answer will make it clear whether it is possible to recover data from a flash drive or not.
To do this, you need to go to Windows Device Manager.
In order to enter it, you need to click right click on the shortcut of my computer on the desktop or in the start menu, go to properties, click on device manager.
After that select disk devices.
We got to the device manager and the disk devices tab. If your flash drive or memory card appears in this list, then it is highly likely that you can recover data on it. If there is no flash drive there, then the memory card controller is most likely burned out. I recommend trying to connect your USB device to other computers.
If nothing changes and the flash drive is still not visible, then the problem is probably a faulty controller. It’s unlikely that you will extract data from such a USB device; you can, of course, contact special institutions that do this (they are not in all cities), but they will charge you a tidy sum for the work. So think about whether you need it or not.
Your flash drive is visible as a device, but it does not appear in my computer or Explorer, or asks to be formatted. To do this you need to go to disk management. To get into it you need to do the following actions. Here are screenshots for clarity:
The device is displayed, writes its volume and file system - it is ready for use and functions normally.
The device is displayed, shows its capacity, but does not display the file system and writes “not defined”. In order to use it, you need to right-click in the Not Defined window and select Format. You can check the box quick formatting and click OK. After the device is formatted, it should work in normal operating mode.
Displayed as removable device, says no media and does not show the file system. All these parameters indicate that this device is not working properly, there is internal or external damage to the controller. You can hardly read information from such a flash drive without special expensive equipment.
Power indicator
When you connect the flash drive to the computer, a small indicator on the USB device should light up. If it lights up and starts blinking, then everything is fine with the flash drive, but not with the operating system, you need to look for the reason in it. If the flash drive indicator does not light up, then the problem may be in the device itself or the connected port of the computer.
Front USB ports
There have been cases when a flash drive is connected to a computer via the front USB ports, but the flash drive does not work. Perhaps these front usbs are turned off or they forgot to connect them to motherboard.
Not enough power
Nutritional deficiencies mainly occur when connecting hard drives through the front USB ports of the computer, hubs and hubs. It is best to connect such devices directly to usb connectors on the motherboard, that is, at the back of the computer. If you are using a USB hub or hub, then disable unnecessary devices, maybe this will help. The reason may also be a low-power computer power supply.
USB disabled in BIOS
This problem is rare. Mainly in computer clubs and similar entertainment establishments. What is it for? To prevent a person from introducing viruses and downloading different programs and not necessary information on computer. This is more of a protective measure. If this home computer, then you need to go to the BIOS settings and check the box to enable the launch of usb devices in the motherboard.
USB device not recognized
The usb device is not recognized and when you connect a flash drive, the operating system gives it an already used letter (volume label in use). This does not always happen; there are other cases. In order to fix this you need to go to the computer control panel.
I showed how to enter it above, or you can open the Run window - the keyboard shortcut Win + R (the checkbox between Ctrl and Alt plus the letter R) and type the command diskmgmt.msc. Go to disk management, find required device- flash drive, right-click on it and select Change drive letter or drive path. In the window that appears, you can add or change this letter.
Outdated drivers
It is possible that you outdated drivers- update them. To do this, you need to find out what manufacturer and model of your motherboard is. Usually written on the packaging box, if you saved them, of course. If not, then use Everest program or Aida. Using them you can find out the model of your motherboard and much more. useful information about your computer. After you have found out everything, you need to go to the manufacturer’s official website, find the required motherboard and download drivers for the chipset and usb device, if there are any.
Viruses
There have been cases where the computer does not recognize the flash drive due to viruses that have appeared in your operating system. For this I recommend using good antivirus programs and do full check for viruses at least once a month. If you don't have it, you can use free antivirus Kaspersky Yandex version, or purchase a paid product.
Different file systems
This happens, but very rarely. Your computer does not see the flash drive due to a conflict between the file systems of the computer and the flash drive. Most flash drives work in two file FAT systems and FAT32, and hard disks to NTFS.
You can try formatting your flash drive in a different format such as FAT32 or NTFS. Maybe after this everything will work fine.
Helpful information. On a flash drive in FAT and FAT32 format, you can upload information in one file of no more than 4 Gigabytes, and on a hard drive much more. Therefore, if you encounter such a problem, be prepared for it and keep it in mind.
And for dessert, watch a short video tutorial on how to make your computer see a flash drive and hard drive. For convenient and enjoyable viewing, I recommend watching this video in full screen, that is, in full screen mode.
The computer does not recognize the flash drive and hard drive
Has it ever happened to you that you were just holding keys, a flash drive, a pen in your hands, you were distracted for a minute - and now it seemed to have fallen through the ground? Everything has already been inspected and double-checked ten times, all things have been moved from their places, everything on tables and bedside tables is turned upside down - and the necessary thing seems to have evaporated... And there is a more long-lasting option: sometimes you hide some particularly valuable thing so deeply, It's not like thieves - you won't find it yourself. And she lies somewhere, the scoundrel, but where? We offer you 10 popular methods that will help you find your lost item.
1. In Rus', it was believed that things disappear from sight for a reason - the brownie is playing with you, wants to joke. Try saying while searching for things: “Brownie, brownie, play and give it back!” and at the same time clap your hands. It’s not clear why, but most of the things that were just lost are found right there. Maybe psychologists will say something smart about concentration, or maybe the brownie really exists? You decide!
2. The second, no less well-known method: tie a handkerchief to the leg of a chair. Perhaps the principle of switching attention is at work here. You concentrate on another problem for a second, and meanwhile the solution to the first one pops up in your head. The main thing is that it works!
3. Another simple way is to simply turn the glass or cup over (empty, of course). It is believed that the item will be found instantly.
4. And we often use this method without any prompts - start talking to the “refugee”, call her and persuade her to be found. True, first make sure that no one hears us, otherwise your family may think that you are missing a couple of balls in your head.
5. Didn't work simple methods? Well, it's time to turn to real practical magic. In the evening, place a purple light in front of you, light it and mentally imagine the lost thing. If nothing comes to mind, start looking in the direction where the wax drips from the candle.
6. If you have a copper cup, ashtray or incense burner in your home, place dried motherwort, lavender and wormwood in it. Add some alcohol and set it on fire. Fumigate your apartment with this smoke and think that what you lost will be found soon.
7. If you are lucky enough to meet a pet spider (and not squeal at the same time), then ask him to find your loss and blow lightly. And then let your little helper crawls about his business. By the way, house spiders are the guardians of the hearth; they should not be afraid or offended.
8. Imagine the missing item in your mind's eye. Imagine that you are connected to her by a silver thread. Wind the silver ball in your hands and gradually get closer to your goal. The main thing is not to interfere with the mind and logic, but to allow intuition and subconscious memory to work.
9. Walk around your apartment with a pendulum in your hands, constantly asking yourself the question of where your thing is. look in the place where the pendulum begins to rotate. You will definitely find something there!
10. The most the hard way. Before going to bed, take a thread the length of your height, fold it 3 times, then another 7 times and tie 3 knots on it. Place it under your pillow. Either in a dream you will see the place you need, or after waking up, begin to untie the knots one by one - then you will remember.
What to do if none of the methods helped? The answer is simple and prosaic - general cleaning! Here you will find not only a freshly lost thing, but also everything that you have lost over the past Lately. By the way, modern psychological theory says that the order in your home reflects the state of your body and soul. And this is true - if you don’t have enough energy or time to deal with the trash in your apartment, then most likely the same thing is happening in other areas of your life. So grab a broom and go ahead - clean not only your home, but also your life!
The computer does not see the flash drive. Technology cannot work forever. There may be several reasons:
1) the front connectors on the PC are not connected to the motherboard;
2) there is not enough food;
3) system driver failure;
4) viruses;
5) file system conflict;
6) hardware failure of the drive.
Almost all problems can be “treated” with improvised means, namely system utilities computer. Let's look at each breakdown in detail.
Reason 1: Inactive sockets and lack of power
If your flash drive does not open on your computer when connected to the front connectors system unit, check additionally the jacks for connecting a headset (headphones).
If they are silent, it means that the manufacturers did not bother to connect the socket block to the motherboard when assembling the PC. If the computer is under warranty, feel free to complain to the seller about poor quality assembly. Alternatively, use the rear ports.
The second nuance is insufficient power supply to the connectors, which is why the flash drive “blinks”, i.e. randomly recognized/disappears. Most likely, the assemblers are to blame for cheating when connecting them to system board, not completely recessing the cable into the corresponding groove.
In this case, you need to visit again service center or the seller. But if you have experience building a PC, try doing it yourself.
If after all the manipulations absolutely nothing happens, the problem lies elsewhere.
Reason 2: drivers
Each flash drive initially stores a driver in memory, which is automatically installed when the device is connected. But Windows can periodically crash, causing the average user to suffer. To correct the situation, the following set of manipulations will be required.
To begin, right-click on “My Computer” and go to “properties”.
A list of several tabs will be displayed, from which you need to select “Hardware” and go to “Device Manager”.
Scroll through the list until we find USB controllers. Expand the list by clicking on “+” and see full list devices that are connected or have been connected once through the required connector.
Next, you will have to play the so-called attentiveness test. We connect the drive and wait until the list of drivers blinks. One of the components will change its name. This is our culprit and must be eliminated.
To do this, right-click on it and select “Delete”. Confirm your intentions, and then reinsert the flash drive. The driver will be picked up automatically. In the vast majority of cases this helps.
Reason 3: viruses and trojans
Although the system requires checking devices for spyware, few people do this, and they pay for it by causing the system to malfunction. It’s very simple: the virus replaces the “native” autorun driver with a modified one, which can result in the message “Access denied” appearing.
Therefore, if the flash drive does not boot , we do the following.
Open "My Computer" and address bar We write down the letter of the device (everything is as in the screenshot, preserving the characters). Your drive letter may vary.
So, you got inside. But now you have to do hidden files visible to get to autostart. To do this, select “Service”, and from the list that opens, select “Folder Options”.
We are interested in the “View” tab. Scroll the slider to the very bottom until you find the “Hide” setting system files..." We remove the checkbox from this item, simultaneously switching the system to the ability to show hidden files.
Have you checked? Great. Re-insert the long-suffering device and continue working.
Reason 4: Partition conflict
Other incidents also happen. For example, you inserted a drive into your computer. The system recognized him and issued the corresponding “tyn-dyn.” A characteristic icon has appeared on the taskbar at the bottom, but for some reason Windows refuses to assign a partition letter. How to deal with this?
To begin, click Start and go to Control Panel.
On the left side of the window, for ease of use, select “Switch to category view.” Although if it is already turned on, there is no need to perform any manipulations. We need to get into “Administration”.
Important: All manipulations must be done only on behalf of the administrator. Otherwise, the system will not accept the changes.
Select "Computer Management" double click mouse and move on.
Before us " back side» systems with various settings. Do not under any circumstances engage in ad-libbing if you do not understand it. Just follow our advice.
Flash drives are now the main means for transferring and storing information, surpassing previously popular ones. optical discs And external hard drives. Some users, however, have problems viewing the contents of USB media, particularly on laptops. Our material today is intended to help such users.
First of all, we note that the procedure for opening a flash drive for further viewing of files on it is the same for both laptops and desktop PCs. There are 2 options to view the data recorded on the flash drive: using third-party file managers and Windows system tools.
Method 1: Total Commander
One of the most popular file managers for Windows, of course, has all the necessary functionality for working with flash drives.
As you can see, there is nothing complicated - the procedure takes just a few mouse clicks.
Method 2: FAR Manager
Another outsider "Conductor", this time from the creator of the archivist Evgeniy Roshal. Despite its somewhat archaic appearance, it is also perfect for working with removable drives.
There are also no difficulties in this method, except for the interface that is unusual for the modern user.
Method 3: Windows System Tools
On operating systems from Microsoft official support flash drives appeared in Windows XP (on previous versions it is necessary to install additional updates and drivers). Consequently, on current Windows operating systems (7, 8 and 10) there is everything necessary for opening and viewing flash drives.
This method suitable for users who are accustomed to the standard "To the conductor" Windows doesn't want to install additional software on their laptops.
Possible problems and methods for eliminating them
Sometimes when connecting a flash drive or trying to open it for viewing, various types of failures occur. Let's look at the most common of them.
- The flash drive is not recognized by the laptop
The most common problem. It is discussed in detail in the corresponding article, so we will not dwell on it in detail. - When connecting, an error message appears: “The folder name is incorrectly specified.”
An infrequent but unpleasant problem. Its appearance can be caused by: software glitch, and hardware failure. Check out the article below for more details. - The connected flash drive requires formatting
Probably during previous use you removed the flash drive incorrectly, which caused it to malfunction file system. One way or another, you will have to format the drive, but it is possible to extract at least some of the files. - The drive is connected correctly, but the inside is empty, although there should be files there
This problem also arises for several reasons. Most likely, the USB drive is infected with a virus, but don't worry, there is a way to get your data back. - Instead of files on the flash drive there are shortcuts
This is definitely the work of a virus. It's not too dangerous for your computer, but it can still cause trouble. However, you can protect yourself and return files without much difficulty.
To summarize, we note that, subject to use safe removal drives, after working with them, the likelihood of any problems arising tends to zero.
It often happens that a person loses an object or thing at home: keys, watches, bracelet, passport and much more. The search often takes quite a lot of effort and nerves. Sometimes it seems that the whole house has already been searched, but the missing item has not been found.
Lost search options: vacuum cleaner
If a small item has fallen, a vacuum cleaner is suitable to find it. Disconnect the brush from the vacuum cleaner, and in its place, attach and carefully secure an ordinary sock. Turn the vacuum cleaner on to maximum and slowly move the tube over the area where the desired item might have fallen. If you are lucky and the missing item is found, then take it from your sock and turn off the vacuum cleaner.
Focus and think
When the dimensions of an object do not allow you to use a vacuum cleaner, do not despair. Try to pull yourself together, stop being nervous and panicking. Sit down, think, look around the room and those places where the wanted item may be located. What often happens is that it is in front of your eyes, and your lack of concentration prevents you from detecting it.
If all else fails, close your eyes and remember where last time saw the loss. For example, you lost a flash drive: remember step by step where and when you used it and where you put it away. You inserted the flash drive into the computer, carried out certain actions, took it out of the connector and put it somewhere. Now open your eyes sharply and go to where you left the thing. If it is not there, then continue searching.
Refer to your home
People always blame themselves, relying on their inattention and absent-mindedness. But it is worth remembering that the matter may be due to peculiar changes taking place in your home. The room where people live is considered the place where the energy associated with the life of each family member is concentrated. This same energy leads to you getting tired, filling your head with thoughts about business and forgetting about home. The roof senses this, so a kind of imbalance of energy and objects arises.
At times like these, you feel clumsy, for example, trying to turn on a light where there is no switch or placing a cup of food on the edge of the table so that it falls. It seems to you that there is chaos and asymmetry in the house.
So, in order to find something, you need to turn to your home. No, this does not mean that you need to torment yourself every day with general cleaning and apartment maintenance. Just live in the house, feel its warmth, thank it for the fact that you have it, and you can relax in it, do what you love, cook food and be its owner.
Appease the brownie
The next step is to please the spirit of the house. Everyone knows that brownies love to make fun of their owners. This is especially true when you have recently moved into a house, in new buildings, and when you do not take care of the house. The spirit of the house can move objects, hide them because he doesn't like something or is worried.
If you cannot find your favorite earrings and think that these are the tricks of the brownie, then try to appease him: feed him something tasty, floury and sweet. Place a piece of sugar, cookies or a little butter in the eastern part of the house (this is where the spirit of the house lives). The result will not be long in coming - the thing will soon be in its place. You can talk to the brownie and ask him to return your item. Believe me, it really works.
Summoning with a thread
Our ancestors left us one more universal method search for lost things: arm yourself with a thread or rope and tie it to the table leg in the kitchen.
Such actions encourage the lost item to return to its place. Most things disappear as a result of temporary changes, so it is precisely summoning the thing that will return it to its owner.
Pendulum to the rescue
Searching with a pendulum is also quite common among Old Believers. You can take a special pendulum for dowsing or make it yourself from a weight suspended on a rope. While holding the pendulum, start thinking about the lost thing, about its appearance and accessories. Make a wish in which you express that you want this thing to be found. Walk around the room with a pendulum in your hands. When you feel his movement, go where he leads you. This is how you can find the location of a lost item.If not a single piece of advice helped you, and the item was never found, but you are sure that it is in your house, then use the last method, which guarantees that you will find it - spring-cleaning premises. This method is good because your house will begin to shine with cleanliness, and because the loss will certainly be discovered.
Be sure to use the tips given above, then you will easily find exactly what you need and exactly where you do not expect it. Try not to lose your favorite things and household items.
