Programs for recovering flash drives qumo. Qumo flash drive data recovery

AT modern world people are used to using flash drives to transfer information. A few years ago there were disks, and before that there were floppy disks. Compared to these already obsolete devices, a flash drive is much more productive and smaller in volume. Of course, with such popularity, they began to develop rapidly, and now you can find an external drive from 1 GB to 516 GB.

Unfortunately, they, like any other technique, can break. This happens for various reasons: they took out a flash drive during recording or it broke from heavy loads etc. Users began to look for options on how to repair a flash drive. If the problem is related to the hardware, then it can simply be thrown out. Another case is software failures. In this case, you can try to restore the external drive. Do not immediately carry your USB drive into service center, since it is not difficult to bring a flash drive back to life, the main thing is to be guided by the rules. Let's look at how to repair a flash drive yourself.

Flash drive won't open

You may have connected a USB flash drive, the computer sees it, but errors occur when you try to open the content. If the computer issues "No access", then most likely it is necessary to clean the external drive from viruses.

What is the problem? After malicious files penetrated the flash drive, they created the autorun.inf file. He is the reason why the external drive does not start.

How to repair a flash drive? In this case, you need to check the external drive with an antivirus. After you remove the malicious files, we need to manually remove the autorun.inf file. Go to "My Computer" and right-click on the flash drive. Then select "Open". A flash drive will open in a new window, we just have to delete the malicious file.

USB stick not formatted

The reason why the flash drive does not open may be a memory failure. How to repair a flash drive? In this case, it is enough to format the external drive. Unfortunately, all content will be erased.

Go to "My Computer" and right-click on the external drive. Next, select "Format". Unfortunately, this method does not always help. If you were unable to restore the external drive, then you need to try the second method.

So, we need to go to the "Disk Manager" directory. To do this, press the key combination Win + R. In a new window, enter the command diskmgmt.msc and click "OK". The "Disk Manager" will open, where we need to select the flash drive and click "Format".

on the computer

To make sure the problem is external drive, you need to get it and try to insert it into other USB connectors that are on motherboard. If the problem persists, then you need to check the USB drive on another computer.

How to repair a micro sd flash drive? First you need to check it in other USB connectors. If the problem persists, then perhaps the problem lies in the card reader. Try to change it.

If the external drive is detected on another computer, then you need to try uninstalling the drivers. How to do it? Go to the "Control Panel", where we select the "Device Manager" directory. In a new window, look for the line "Memorable USB device and uninstall the drivers.

After the done actions, disconnect the USB flash drive and restart the computer. After that, we connect the USB drive and install new drivers.

If the reinstallation did not bring results, then you need to clean the registry branches. They contain all the information about your device. First we need to collect this information, or rather, find out a few parameters (PID and VID). To find out this data, you need to return to the "Device Manager" directory and right-click on the USB flash drive. Go to the "Details" item, where the device code will be displayed.

After that, press the key combination Win + R, in a new window, enter the regedit command. So we will open the registry editor, where we need to find two parameters, the first one ends with the word USB, and the second USBSTOR. We open these directories and look for identifiers, after which we delete them. We restart the computer and check the performance of the external drive.

External drive is detected, but dimensions are not displayed

If you find yourself having such a problem, then there have been memory failures. How to repair a flash drive? In this case, you need to download the ChipGenius program. This way we can find out the VID and PID of your external drive. After you have found the flash drive chip model, you need to go to the flashboot.ru website, where you need to enter the received data. We start the search. So what have we found? These are the appropriate drivers and utilities for your removable drive. After installation, your flash drive should work.

How to repair a USB flash drive if nothing helped

Of course, there may be various problems with an external drive that do not allow you to restore a flash drive for the problems already described. Is there another way to return removable drive to life. However, this the way is fine It is for a flash drive, a memory card that cannot be restored in this way. If you are tormented by the question of how to repair a Transcend flash drive, then try this method.

Where to start? Take your USB drive and remove the plastic cover. We need to put our device into test mode. Turn the flash drive over as shown in the picture. In the corner is a small button that will need to be closed. As a rule, it is necessary to close contacts 29 and 30. How to do this? Take a needle and press in the right place.

We insert a removable disk so that the computer detects the USB flash drive and it becomes available. Only after that we open the contacts. However, do not disconnect it from the computer, as it will not work yet. Next, you need to install drivers and utilities, we have already covered how to do this.

Conclusion

After the above steps, your USB device should work. If this does not happen, then there may have been problems with the hardware. In this case, it is easier to throw it out than to restore it. As you have already noticed, repairing a flash drive is not difficult if the problem lies in the software part. However, in order to quickly and efficiently restore your device, you must immediately identify the problem.

A flash drive is a storage device that can be connected to any PC via a USB interface. Quite often, this device stops working normally. What should I do? Below will be considered the most effective ways flash drive treatment and corrections of typical errors when working with the device.

Follow all steps sequentially - if the first method did not help, move on to the next one and so on.

What to do if the flash drive stops working

In the modern IT industry, the KISS-principle is relevant in a narrow circle, meaning "Make it easier!". Without special need, there is no need to edit the registry, use complex hardware troubleshooting methods, or try to implement other procedures - it is worth starting with the simplest steps.

1. Try connecting the flash drive to another PC, laptop or other device for communication via USB interface. If the flash drive does not work, then with 100 percent probability it can be argued that the problem is in it - and it is necessary to immediately move on to utilities for repairing and fixing a flash drive.
2. If the flash drive works on another computer or is at least detected by Windows (but "Explorer" and "This / My Computer" do not appear), then you need to Troubleshoot the OS or file system using the instructions below.

1. Disconnect the drive by pulling it out of the USB connector.
2. Shut down the PC by selecting the Shut Down option.
3. Disable system unit from the mains 220V, hold down the power button for 5 seconds - this will remove the residual charge on individual motherboard modules.
4. Connect your computer to a power outlet.
5. Turn it on, wait for the download to complete and insert the USB flash drive.
6. Try connecting it to a different connector, especially if external front USBs were previously used for this task. Best option- rear ports
7. Sometimes the cause of flash drive failures is assigning it system ID in the form of a letter, or the disappearance of this parameter altogether, to fix an OS problem, use the Disk Management utility

Utilities for flash drive recovery

Be sure to check the flash drive through utility"USB Troubleshooter" from Microsoft - it is not bundled with the OS, but is available for download from the official portal at the link free, and only works with OS W7 and above.
Using it is simple - run the program and click "Next".

After that, the software will try to find and fix typical problems with the display of the flash drive in the system.

If you hear a characteristic sound when you connect the device, but it does not appear in the "Explorer", then open the "Device Manager"

Often problem with reading USB flash drives appears after updating the operating system - it is provoked by incorrect registry entries left after connecting physical storage media.

Looking for them manually is quite long and better take advantage special program to find and clean non-working keys in the registry.

Best suited for this Vit Registry Fix utility (free and does general search and cleanup) and utility USBOblivion (free and cleans all data about previously connected flash drives from regedit).
Main advantages: The interface is intuitive and there is Russian localization.
Download the program run automatic search, after its completion, start the cleaning (after checking the sections on saving all changed .reg keys in the archive in order to “roll back” the operation if necessary).

Sometimes the flash drive does not work due to driver incompatibility for USB 2 and 3 versions. In this case, download updated versions on the official website of the motherboard manufacturer.

Why does not see the flash drive. If the PC does not accept any flash drives, then you need to completely reinstall all drivers for USB drives.

The easiest way to do this is through the "Device Manager" (hold Win + R and enter devmgmt.msc, click on "OK"). Find the “USB Controllers” section in the drop-down list and sequentially delete (right-click on the object, “Delete” item) the USBHostController, GenericUSBHub and USB Root Hub subsections, then update the current hardware configuration and restart the PC.

As an add-on, run full check the entire system.

1. Run the registry (hold Win + R, type regedit and confirm the action by clicking on "OK").
2. Right-click on the HKEY_CURRENT_USER key and select Find, then type Explorer in the search box. If the folder contains NoDrives, then you need to select and delete it (using the Delete button). In addition, in the same registry editor, search for the StorageDevicePolicies parameter (under the HKEY_LOCAL_MACHINE key) and delete it (if any).

Sometimes all the above methods do not give any tangible result.

If the flash drive is identified in the system (at the level of determining an unknown connected device), then you can try to restore the normal operation of the device, formatting it in a special way using a third party HDD Low Level Format Tool .

In this case, work with the device occurs at the level of physical sectors, and not file system(as with regular formatting), which guarantees:

1. Wipe bad sectors
2. Troubleshooting any software issues
3. Permanent deletion of all data from the media.

The program is free and available for download from the official website. After installing and running it, select the required drive, click Continue.

Find the Low-levelFormat tab and accept the operation by clicking on Formatthisdevice.
The duration of the procedure depends on the type of flash drive and its capacity, on modern PCs the process takes an average of 30-60 minutes. Once completed, you should safely remove the device and restart your computer.

I somehow fell into the hands of a flash with a Qumo driver. A common problem is that it does not format, does not open, shows the RAW file system and 0 MB on the disk. Well, I think now I’ll get even with her and quickly please the “happy owner” of this device, since he was already going to throw this drive away, I had to convince him that everything was not so bad, and if you pray more often, maybe we’ll do it. The drives had to be restored more than once, so that a pre-prepared plan of action was already outlined.

First of all, it was decided to use a very useful utility HPUSBFW (full name HP USB Disk Storage Format Tool) - this utility is designed to help with usb formatting drive, despite the fact that it can also be formatted into the NTFS file system. Very often helps, while standard means Windows can't handle it. But in our case nothing happened, namely in this program the error was of the type “write protection” (.... write-protection) . Standard Tools Windows formatting XP and Windows 7 threw a "formatting error" error or something like that. But this is not the time to worry about the first failure, the good thing is now USB Flash The disk costs little and anyone can afford to replace it quickly.

Next, a bunch of recovery programs were tested, such as JetFlash, Flash Doctor, PeToUSB and many others. I tried everything that came to hand, but it makes no sense to list everything, since again there was no result. Therefore, when I was tired and already rather fed up with restoring this device, it was decided to use the service utility, which was already 90% supposed to help and please the owner.

To find a service utility for your flash drive, you need to know which controller it is running on. In general, sometimes a simple name of the device and the Internet is enough to search for this information, but this time I disassembled the drive and saw firsthand which controller it costs, besides, it turned out to be necessary to determine the memory chip.

So the data of the device:

Controller: SK6211

Memory chip: I29F64G08FAMC1 (I wrote from memory, since this flash drive is not at hand, its owner is in this moment enjoys her work, so the last 5 characters may differ ...)

The service tool that will do the whole thing for us will be called SK6211_PDT_20090828. This utility works with the SkyMedi controller, and we have just such a controller, as indicated by SK in its marking. There is a manual for working with the program, it will not be particularly difficult to find it. I definitely recommend reading it, because you can’t do it without it, unless of course you use it for the first time. Everything would be fine: I read the man and recognized the memory chip, but the trouble is in the SK6211BA_Skymedi Flash Support List _20090828.xls file, which helps to find the Code Bank for your flash drive, there was no such memory chip as mine. Therefore, after starting the program, try to select the I64G profile, only after that click on the Auto LLF button ... This is, of course, if your device has been determined ... Otherwise, you will have to lock your legs on the controller ...

Read what to do if Windows does not display the connected device. How to restore the functionality of such a device, if the reason is in it. A USB flash drive or any other USB drive should be automatically detected by the computer and displayed in Explorer and the "This Computer" folder after connecting to the USB port.

Problem Diagnosis

The first thing to do if connected USB disk not shown in file manager Windows must check tool Disk Management.

In order to open Disk Management in Windows 8/10, right click on the menu Start and choose "Disk Management". In Windows 7, press the combination Windows keys+ R to open dialog box "Run" and enter the command in it diskmgmt.msc.

Check the list of disks in the window Disk Management and find the USB drive that is not detected. It should show up here even if it's not in the folder "This computer", and match in size. Sometimes it is defined as "Removable device", but not always.

If you do not see your disk or flash drive even in Disk Management, then try the following:

• Turn on the disk, if there is such a function. Some external hard drives have a separate power cable or are switched on using a separate dedicated key.
• Connect your device to another USB port. Disconnect the flash drive from this USB port and connect to another. One of the USB ports on your computer may have failed.
• Connect your device to a computer without a USB hub. If the flash drive is connected to the computer via an extension cable or USB hub, try disconnecting it from it and connecting it directly to the computer. Perhaps the reason is in the hub.
• Try another computer. Connect the flash drive to the USB port of another computer and see if it is recognized by it. If the device is also not detected by another computer, then most likely the problem is in it.

Solution

If the problem options described above do not apply to your case, then your problem will most likely be solved using one of the methods described below. Depending on what you found in Disk management, there are solutions to the problem that has arisen with the definition of an external storage medium.

If Windows sees the disk, but cannot read it, then it means that it has a file system that it does not support. In this case operating system prompts you to format the drive before using it. But do not rush to do it! This will destroy all your data.

If other computers see a flash drive, but yours does not

In the event that other computers detect your USB drive, but yours does not, then most likely there is a problem with the device drivers.

To check this, open Device Manager and look for Disk devices and USB controllers. See if there are any devices marked with a yellow exclamation mark in these sections. If there is such a device, right-click on it and select Properties. The properties will contain information about the error and the status of the drivers.

To fix the problem with the driver, right-click on the device, select Properties / Driver / Refresh.

If the disk is visible in Disk Management

If the disk is visible in Disk management, but it does not have a letter, it is for this reason that it may not be displayed in Windows Explorer. In order for the system to start displaying it in Explorer, such a disk must be assigned a letter.

To do this, right-click on it and select "Change Drive Letter or Drive Path". If there is no such item in the pop-up menu, then this may be due to the absence or unsupported type of media file system.

In the menu that opens, you will see that the drive letter is not assigned - assign it. To do this, select Add / / Ok.

If the disk is visible in Disk Management, but it is not allocated

If the disk is visible in Disk management, but it's Unallocated, which means it's not formatted. In order for such a disk to become operational, right-click on it and select "Create Simple Volume".

Select the maximum suggested partition size and assign a drive letter suggested by the system. After that, the disk will be normally detected by the system and ready for use.

If the drive is visible in Disk Management but cannot be formatted

If for some reason the disk cannot be formatted, then to restore its performance, you can completely clean it, and then re-create the partition.

Note. As a result of such manipulation, all data from the disk (as well as flash drives or memory cards) will be permanently deleted. Therefore, take care of their safety in advance - scan a disk or flash drive using Hetman Partition Recovery, and save your data to a convenient place.

To clean up the disk open command line as administrator and clean it up with diskpart command − clean.

There are a huge number of reasons why a flash drive does not work, and there are also a lot of degrees of malfunction of your drive, depending on which the available number of ways to repair such equipment changes.

Why are flash drives so popular?

It's no secret that USB drives are extremely common these days. This is no longer just a means of storing data, but a full-fledged accessory that follows its owner everywhere. If literally 10 years ago only wealthy people went with flash drives up to 2 GB, today almost everyone has modern man There is a flash drive with a capacity of 16 GB or more. However, despite the fact that modern people are often faced with the fact that a flash drive does not work, not everyone is trying to figure out why this is happening, how to fix it later.

Advantages and disadvantages

Not everyone understands why USB drives have become so widespread these days, but this happened due to the huge number of advantages of such drives:

• Compactness.
• Absolutely silent operation.
• Sufficiently large overwriting potential.
• Resistance to external influences, which far exceeds standard hard drives.
• Reliability of data storage for a long time.
• Versatility and availability.
• Sufficient data storage.
• Relatively low cost.

It is this popularity that has led to the fact that the flash drive does not work for many users, because the more people use such devices, the more such cases appear. At the same time, it should be noted that, in fact, with all their advantages, such drives also differ in a number of disadvantages, which few people also think about. Quite often it happens that a flash drive does not work due to its breakdown or even complete unsuitability for further use. The user often does not think that it is possible to recover files from such drives, unless, of course, some extremely important data has been lost. But in fact, in the vast majority of cases, instead of buying a new device, you can return the existing drive to work.

Why do they break?

There are many reasons why a flash drive does not work. What to do in each individual situation depends directly on why such a device broke down. There are only three main reasons:

• The flash drive was incorrectly removed from the computer socket.
• The device has exhausted its potential (data can only be overwritten a limited number of times).
• During operation of the equipment, a power surge or voltage surge occurred.

In fact, this is far from full list why the flash drive is not working. What to do in certain situations, specialists are already considering in more detail in some cases, and you just need to know how you could fix the broken device yourself or make it so that specialists can fix it later.

In the vast majority of cases, the controller initially breaks in the flash drive. Determining a breakdown is often quite simple - you insert the device into a specific slot, but instead of displaying a separate disk to which you can copy some information, the system says that you need to completely format new disk, the device is inaccessible, or you see that the drive has been formatted in RAW format.

"Only for reading"

It often happens that the flash drive on the phone or computer does not work, and when you try to access the device, an error pops up with the message “Read-only”. This malfunction is due to the fact that the drive is already gradually starting to work out its life, as a result of which the controller switches the equipment into the so-called memory self-protection mode, which excludes the possibility of writing in order to keep the physical structure of the device in a normal state. But at the same time, such a situation often occurs that the blocking occurs for a more banal reason - the controller in your device just broke, so the flash drive does not work in the car, at home or anywhere else.

Of course, this is bad news for those who want to fix the device itself, since in principle it will be impossible to do this, and the only thing that can still be done is to restore information from the drive, which is what many people do.

What to do if the device is broken?

As mentioned above, in order to determine what exactly needs to be done in a given situation, you first need to understand why the flash drive does not work on the computer. In particular, there are two options:

• Recovery of information from the drive.
• Repair of the device itself.

It is often necessary to choose among these options for the reason that in some difficult situations, when information is restored, the device remains unusable in the future, while all information stored in the drive is lost during the repair.

Guarantee

When you buy a flash drive official store, in any case, you should be provided with a specialized warranty card, which indicates the conditions and, of course, the terms in which you can get free repair or an exchange if you suddenly find that the micro-flash drive is not working. If the USB drive failed during this period of time, then in this case you have full right take it back to the store and demand an exchange for a new device for free. At the same time, you must initially understand that no one will restore information from your drive, they will simply provide you with a new one, since it makes no sense for the store to carry out repairs, and even more so to restore from your device.

Repair of physical faults

Assuming that the device itself was not badly damaged, and you roughly understand the reasons for the malfunction and can sacrifice data, then the first thing you should do if the USB flash drive does not work is to format it. However, you should make an informed decision: are you really ready to lose data, or would you still like to recover it. If you still decide that the files that the device stores are really important to you, then in this case, in case of physical damage, you will need to contact the company in order for the information to be returned to you using special equipment. However, as already mentioned, after that you will no longer be able to use the flash drive.

How do specialists restore?

In principle, it is recommended to contact specialized companies if you are faced with such a situation that the flash drive does not work. How to restore will be decided by the appropriate specialist, however, in the vast majority of cases, especially when it comes to physical damage, specialized equipment is used to restore printed circuit boards or completely remove the memory chip from the board, and the data will already be extracted directly from it.

What is needed for repair?

If you still decide that you can risk the data on the device if the flash drive on the computer does not work, you will need to have the following tools:

• Soldering iron.
• Old USB cable.
• Pliers or cutters.
• Small flat screwdriver.
• Magnifying glass.

It should be noted right away that you can only carry out repairs on your own if it is a broken connector. If for some other reason the micro-flash drive does not work, only a qualified specialist who has experience in this field and specialized diagnostic equipment will understand what to do.

How to repair?

Initially, you should use a screwdriver to release the drive from the protective case by unscrewing the cover from it. Now you should take a magnifying glass and use it to look at the printed circuit board in order to determine why the flash drive is not working. If there is any damage to the contact pads, you can no longer cope with the problem on your own.

Use wire cutters to cut the end of the cable, while cutting off the female end if it is not a male-to-male plug. Now strip approximately 0.6 cm of each of the wires inside the cable. If you don't have an extra cable, you can try soldering the pieces with electrical wire to each of the prongs for the broken connector. This way you can make your own mini cable.

Now each of the wires should be soldered to the pads. It should be noted that the wires must be connected in right order from left to right - black, green, white and then eventually red. If you used your own wires instead of a cable, then just solder each individual wire to the appropriate pads, regardless of color. Now you just have to connect the other end of the cable, and connect the device to your computer. If the device is determined, you can enjoy the repair done.

If you tried to connect, but the flash drive is not recognized, then in this case the problem lies in something else, and with the naked eye a layman will not be able to determine this problem. That is why you should either consider enlisting the help of qualified specialists who can restore the data or even the performance of the drive, or you can simply throw away the device and think about which one to buy next.
