The cf flash drive is not detected. Do-it-yourself USB flash drive repair: we fix hardware and software problems. Mechanical damage and ways to eliminate it

Greetings to all blog readers!

Probably most people who work with a computer more or less often have a flash drive (or even more than one). Sometimes it happens that a flash drive stops working normally, for example, due to unsuccessful formatting or as a result of some errors.

Quite often, the file system can be recognized in such cases as RAW, the flash drive cannot be formatted, and it cannot be accessed either... What to do in this case? Use this small instruction!

These instructions for restoring the functionality of a flash drive are designed for the most various problems With USB media, except for mechanical damage (the manufacturer of the flash drive can, in principle, be anything: kingston, silicon-power, transced, Data traveler, A-Data, etc.).

And so... let's get started. All actions will be described step by step.

1. Determining the parameters of the flash drive (manufacturer, controller brand, amount of memory).

It would seem that it is difficult to determine the parameters of a flash drive, especially since the manufacturer and amount of memory are almost always indicated on the flash drive body. The point here is that USB drives of even one model range and the same manufacturer can have different controllers. A simple conclusion follows from this - in order to restore the functionality of the flash drive, you must first accurately determine the brand of the controller in order to choose the right utility for treatment.

A typical type of flash drive (from the inside) is a board with a microcircuit.

To determine the brand of the controller, there are special number-alphabetic values ​​specified by the VID and PID parameters.

VID - vendor ID
PID - Product ID

They will be different for different controllers!

If you don’t want to kill the flash drive, then under no circumstances use utilities that are not intended for your VID/PID. Very often, due to an incorrectly selected utility, a flash drive becomes unusable.

How to determine VID and PID?

The easiest option is to launch a small free utility CheckUDisk and select your flash drive from the list of devices. Next you will see all the necessary parameters to restore the flash drive. See screenshot below.

VID/PID can be found without using the utility.

To do this, you need to go to Device Manager. In Windows 7/8, this is conveniently done through a search in the control panel (see screenshot below).

In the device manager, the flash drive is usually marked as “USB Mass Storage Device”, you need to right-click on this device and go to its properties (as in the picture below).

In the “details” tab, select the “Equipment ID” parameter - the VID/PID will appear in front of you. In my case (in the screenshot below) these parameters are equal:

2. Search for the necessary utility for treatment ( low level formatting)

Knowing VID and PID we need to find special utility, suitable for restoring our flash drive. It is very convenient to do this, for example, on the website: flashboot.ru/iflash/

If suddenly nothing is found on the site for your model, it is best to use a search engine: Google or Yandex (query like: silicon power VID 13FE PID 3600).

In my case, the Formatter SiliconPower utility was recommended for a flash drive on the flashboot.ru website.

Actually, that's all. Of course, this recovery instruction is not the simplest (not 1-2 buttons to press), but it can be used in many cases, for almost all manufacturers and types of flash drives...

All the best!

Hi all! In this article we will talk about such cases when a flash drive is not detected on any computer at all. So what will it be detailed instructions on restoration.

I must say that the experimental USB drive is already well known to you from previous publications, since not so long ago we recovered information from it and . For those who haven't read it yet, you can check it out.

The situation has changed in better side only until I came across a good old utility called Hard Disk Low Level Format Tool. It was she who helped solve the problem and save money by bringing the drive back to life.

So what needs to be done. The first step is to install the above program from the official website of the developers. It is small and weighs very little. Launch it and select “Continue for free”:

Then, in general, our flash drive appears, which in the most Windows system 10 is not defined at all. That is, it is nowhere and everything is here:

Select it and click the “Continue” button at the bottom to proceed to the formatting process. In this case, it is probably not worth warning that all data will be lost as a result of this process. 😉

In the next step, go to the section " Low-Level Format" and click the "Format This Device" button:

After this, the program will once again inquire about the seriousness of our intentions. Here, just like in a registry office, we say “Yes” once again:

That's all, friends, now all you have to do is wait for the low-level erasing process of the USB drive to complete. After this, the long-suffering flash drive was finally detected in the system, but when accessed for the first time, it “asked” to be formatted again. Well, let's not argue:

We are starting the procedure again regular means the great and terrible Windows:

As a result, guys, the flash drive, which was not detected before, has successfully started working. Therefore, we can safely say that the detailed restoration instructions were still a success.

If you still have any questions, ask them in the comments to the publication. And that's all for now and see you again. In conclusion, as always, let's watch another interesting video.

Today, among PC users, there is probably not a single person who would not use items on flash memory. These include USB drives, MP-3 players, memory cards and other devices that use flash memory. At the same time, very often various problems arise with flash drives. Then the computer displays “USB device not recognized”, “Insert disk”, “No access to disk” or “The disk is write protected”, or “Windows cannot finish formatting”. Or it doesn’t detect the flash drive at all. It happens that no serious problems arise with flash drives, but the information is simply accidentally deleted or the flash drive is formatted. How then? On this page you will find everything you need to recover information from a flash drive or repair it yourself. In most cases, it is possible to save the flash drive. And it is almost always possible to restore lost information if rescue measures are taken in time.

USB device not recognized
This kind of glitch sometimes happens to USB driver or with the USB flash drive itself (memory card or MP player), after which the flash drive is not detected in one of the USB sockets. The first thing you need to do is insert the flash drive into other USB sockets or even into another computer to determine which device is not working. If the flash drive is detected in another slot or in another PC and starts working, then the problem is not with it, but with the computer. This way you can understand where to look for the problem in order to fix it. It's clean software problem and it can be resolved by reinstalling the USB driver. In a more complex case, you will have to edit the registry. If you know how to use registry cleaning programs, you can use them. If not, you can edit the registry manually. This is done like this:
Start: run/regedit/OK
Next you need to expand the branches:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR
and clean out all folders whose names contain VID & PID. These registry branches contain records about all USB devices that connected to this PC. If you know the VID & PID of your flash drive that does not want to be detected correctly, then you can only delete the folder that contains the name of your flash drive or its VID & PID. This must be done from both of these branches. If you clear these registry branches of all entries, then nothing bad will happen. Windows will create new entries there itself. If Windows does not allow you to delete folders in the registry, then this can be done using another OS, for example with a Live-CD. In the same way, in a Live-CD you go into the registry and delete folders just like in Windows. Then download yours again Windows version and check the flash drive. Everything should work. You can look at the expanded registry branch

If you accidentally deleted data or formatted a flash drive
After deleting information or formatting flash memory, you can return information using a simple Recuva program. The main thing is that after losing data, do not write anything to this flash drive, otherwise the information can be overwritten by new data.
You can download the program.

Unable to format flash drive
It happens that a flash drive or memory card becomes so glitchy after a failure that you cannot format it using Windows. The PC gives you the message “Windows cannot finish formatting” or something similar. In this case, “Panasonic_SD Formatter.2000” will help you - a small utility that performs formatting. After formatting the flash drive with this program, you can continue to use it.
You can download it.

The flash drive does not open or is not detected
In this case, you should use special programs recovery of flash drives after serious failures. To know which program to use, you must first find out VID & PID chip.
VID– manufacturer identifier
PID– device identifier
You can find out VID & PID with special programs, such as ChipGenius or CheckUDisk. Programs determine VID & PID even if the computer does not see the flash drive.
ChipGenius– a detailed and understandable program from Chinese manufacturers. CheckUDisk is another program for determining identifiers, albeit simpler.
ChipGenius – download
CheckUDisk – download
After you find out the chip identifiers of your flash drive, look for your pair in the table and download the desired program.
There is another program FlashGenius, defining the parameters USB Flash drives according to their markings. FlashGenius detects chip capacity and version, manufacturer, voltage, MLC/SLC type, etc.
You can download it.

If flash drive recovery programs did not help
In this case, when nothing has helped and there is really nothing to lose, you can try more harsh methods - simply short-circuit the microcircuit. You can do it like this. Disassemble the flash drive or device where the flash memory is located, insert the device into USB, turn it on if it requires turning on and close the contacts of the microcircuit with a needle. How to do it

What if nothing helps at all?
If it happens that none of all the methods helped, then things are really bad. If this is an expensive device that uses flash memory, then you can take it to a service center and they will replace the chip. If it’s a simple USB flash drive, then you can safely throw it away. Because after such recovery manipulations, it will no longer be possible to save the information, and repairing an empty flash drive will cost more than buying a new one.

Good luck!

Today, you practically cannot find a person who does not have a flash drive in his arsenal. This device is a universal thing and is used everywhere. On TVs, stereo systems, cars and other devices. The more often we use a flash drive, the faster it deteriorates and the computer stops finding it. In this article I want to tell you several ways to fix the problem of an “unreadable” flash drive.

Case one

Insert the flash drive into USB port in the back. If it doesn’t help, then unfortunately your flash drive is dead.

Case four

You insert the flash drive into the USB port, and it asks you to format it. I'm afraid that in this case you will have to format it, or else it won't work. This could happen if the flash drive was not removed correctly or it was removed during copying, preventing the process from being completed.

Case five

USB device not recognized. There is no need to panic in this case; the cause may be dust or dirt that has stuck to the contact ports. Try inserting the flash drive into another port - it doesn’t read? There are two options: either reinstall Windows or the driver, but it’s better to try the second option - you shouldn’t reinstall Windows right away.

Well, that's all, I have listed the most basic problems that occur when the computer does not see the flash drive.

Hello!

Flash drive on this moment, this is one of the most popular types of storage media (except for the ability to share files over the network).

In fact, a USB flash drive has a lot of advantages: it is mobile (can be put in any pocket), universal (connects to any PC, laptop, gadget), copying/reading information from it is quite fast, etc.

But one small thing happens to them" problem“- sometimes the computer refuses to recognize and see it. There are quite a few reasons for the invisibility of a flash drive, in this article I want to give the most basic ones that I most often encounter in my work.

Also from the article you will learn what can be done to restore the functionality of your device (you shouldn’t always immediately throw it away and run to buy a new one?! 👣).

If you want to buy flash drives at bargain prices, I recommend using Chinese online stores:

Reasons for the invisibility of a flash drive

10 Main reasons and their solutions...

Problem #1: the flash drive is not formatted

This reason is the most common! The fact is that after purchasing a flash drive, you need to format it (very often new flash drives and disks are not formatted at all and therefore they are not visible in “My Computer/This Computer”...).

Solution

It is most likely pointless to go into “My Computer”, because... in some cases you won’t see a flash drive there.

Therefore you need to open "Disk Management" . To do this, press the button combination Win+R (The Run window should appear) , enter the command diskmgmt.msc and press Enter (screenshot below).

Remark! If your flash drive is not visible in Disk Management, go to the 3rd problem.

Find your flash drive in the list (guide by its size and name, for example, "Kingston...8 GB") , then click on it right mouse button and in the appeared context menu choose - " Format... " (example in the screenshot below) .

Actually, that's all. By the way, I recommend choosing NTFS as the file system (because on FAT 32, which is often the default on flash drives, it is impossible to copy and place files whose size exceeds 4 GB).

Problem #2: incorrect auto-installation of drive/flash drive letter

When you connect any disk drive, flash drive, floppy disk, etc. to your computer - it automatically assigns a unique drive letter to your drive, e.g. "System disk C:\" or " Local disk F:\", etc.

Everything would be fine, but sometimes the auto-installation of the letter fails and assigns a non-unique letter to your connected drive. As a result, the drive is not visible...

To solve this, you just need to try changing the letter (this is done quickly and very often solves the lion's share of problems).

Solution

You also need to go to "Disk Management" (how this is done is described above), then select your “invisible” drive, click on it right mouse button and select the function " Change drive letter or drive path ".

To help!

By the way, in some cases, Windows may not assign a drive letter to all connected drives at all. To fix this, use the following recommendations:

Problem #3: Outdated or broken drivers

A very, very common problem is outdated drivers (also sometimes drivers can fail and conflict with each other). It is worth noting that on older computers another problem is possible - the inability to see a flash drive whose size is more than 32 GB.

This can be solved in the following way: first remove the old drivers, then install new ones.

Solution

First of all, open the device manager, where you can see all the devices connected to the computer. To do this, open, then change the view to " Large icons" and select " from the list device Manager " (example in the screenshot below).

To help! Alternative ways to open Device Manager -

Note!

Devices that do not have drivers will display a yellow exclamation mark. In general, it is not advisable for you to have such devices marked exclamation marks(or red crosses).

After uninstalling, click the "" button - it is located at the top of the Device Manager window. After which, your manager window will blink a couple of times, and the drivers will be reinstalled...

Problem #4: the front panel of the system unit is not connected

Very often, the USB ports on the front panel of the system unit are not connected to motherboard(apparently they forgot to connect this socket when assembling the PC). In this case, you simply insert the flash drive into a port to nowhere...

Solution

1. Quite simple: connect the flash drive to the back of the system unit - it always has 2÷4 USB ports. At the very least, it is recommended to do this simply for testing - to confirm that the USB ports on the front panel are not working.
2. Try connecting the front panel to the mat. board If you have never had such experience before, go into system unit I don’t recommend it, it’s better to use the services of service centers.

Problem #5: viruses on a PC or flash drive

Settings for enabling USB ports are usually located in the "Advanced" tab. On opposite point USB Controller need to convert the value to Enabled(i.e. enabled, see screenshot below). Then save the settings and exit (usually F10 key).

You can also just reset BIOS settings to optimal (USB ports are always included in them. At least I have not yet seen the opposite...).

Problem #8: File system error

In cases of file system failure - when you connect a flash drive, you will most likely see a message that the flash drive is not formatted, that it has a RAW file system and Windows will prompt you to do something with it 😊.

In some cases, formatting a flash drive cannot be completed due to some errors...

In general, the problem is with file system- quite “big”, and its solution is not always simple and quick (especially if the flash drive has the necessary data).

Solution

If the data on the flash drive is needed- I don’t recommend formatting it. In general, I advise you not to do anything with it, but take it to a service center. If you want to do everything yourself, then first try to remove your data from it using recovery utilities: Recuva, R.Saver, Easy Recovery Professional, etc.

If the data on the flash drive is not needed (or you have already copied it): I recommend trying to format the flash drive using one special. utilities - HDD LLF Low Level Format Tool.

HDD LLF Low Level Format Tool

A simple utility for low-level formatting of disks and flash drives. In a number of cases, it helps to bring drives back to life, for which there was practically no hope left. By the way, it formats even those disks that Windows does not see or gives reading/formatting errors.

The utility works quite simply: after launching, it will present you with a list of all connected drives to the system, you select the one you need and format it. After formatting, the disk (or flash drive) starts working as it should!

Problem #9: USB port malfunction

It also happens that the USB port becomes unusable. Most often this happens due to frequent and careless use of it: for example, many people sharply pull the flash drive (or USB cable), over time the USB port begins to fit poorly to the inserted flash drive (i.e. there is no contact between the flash drive and the port). As a result, the flash drive is invisible.

Note. By the way, the USB port may not work stably: i.e. you will first see the flash drive, and after you start copying information onto it (or reading it) - you may see an error, or the connection will simply disappear...

Solution

1. Try connecting the flash drive to another USB port, or to another computer/laptop. If the problem is related to the USB port, you will immediately notice the difference...
2. I also recommend paying attention to dirt in the USB port. Often, over time, a layer of dust, plaque, etc. accumulates, which leads to poor contact. If there is a lot of dirt, try removing it with an old toothbrush dipped in alcohol. (perform the operation with the PC turned off!) , and then reinsert the flash drive.

Problem #10: USB flash drive malfunction (for example, after being dropped)

This is perhaps the worst thing that could happen to the drive, especially if it contains important data. Most often, the user guesses that the flash drive may have become unusable, because... before that:

• the drive fell to the floor;
• was dropped into water;
• accidentally touched or hit by any object;
• The drive shows deep scratches, chips or cracks.

In general, when you insert a flash drive into a USB port, the LED on it should light up (most flash drives have one). The characteristic sound of connecting the device should “ring” on the PC. If all this is missing, especially when connecting a flash drive to different devices– then this is a bad sign, most likely there is a problem with the flash drive itself.

Solution

1. Buy a new flash drive (banal and simple 😉, especially since the prices for them are now quite affordable (and they generally cost “pennies”));
2. Try taking it to a service center, maybe the technician will be able to resolder the contacts and it will work again (but I would recommend this method only for). After repairing the drive: using it for important data is not justified!
