Recovery sd flash drive. MicroSD Recovery: A Guide to Recovering Lost Data
Often, users are faced with a situation where the memory card of a camera, player or phone stops working. It also happens that the SD card began to give an error indicating that there is no space on it or it is not recognized in the device. The loss of performance of such drives creates a serious problem for owners.
The most common causes of memory card failure are as follows:
- accidental deletion of information from the drive;
- incorrect shutdown of equipment with a memory card;
- when formatting a digital device, the memory card was not removed;
- damage to the SD card as a result of a breakdown of the device itself.
Consider ways to restore an SD drive.
Method 1: Formatting with special software
The truth is that the only way to recover a flash drive is by formatting it. Unfortunately, without this, it will not be possible to restore its performance. Therefore, in the event of a malfunction, use one of the SD formatting programs.
Also, formatting can be done through the command line.
If all of the above does not bring your storage media back to life, only one thing remains - low-level formatting.
Method 2: Using the iFlash Service
In most cases, you need to search for recovery programs, and there are a huge number of them. You can do this using the iFlash service. To restore memory cards, do the following:
The same applies to other manufacturers. Usually on the official websites of manufacturers, instructions for restoration are given. You can also use the search on the iflash website.
Sometimes data recovery from a memory card fails due to the fact that it is not recognized by the computer. This may be caused by the following issues:
If the memory card is detected on the computer, but its contents are not readable, then
check your computer and SD card for viruses. There is a type of virus that makes files "hidden" so they are not visible.
Method 3: OC Windows Tools
This method helps out when the microSD or SD card is not detected by the operating system, and an error is thrown when trying to format.
We fix this problem using the diskpart command. For this:
Now the SD card can be formatted with standard means OC Windows or other specialized programs.
As you can see, recovering information from a flash drive is not difficult. But still, in order to prevent problems with it, you need to use it correctly. For this:
- Handle your drive with care. Do not drop it and keep it away from moisture, strong temperature changes and strong electromagnetic radiation. Do not touch the contacts on it.
- Properly remove the memory card from the device. If, when transferring data to another device, you simply pull the SD out of the connector, then the structure of the card is violated. You should remove the device with a flash card only when no operations are being performed.
- Periodically defragment the map.
- Do it regularly backup data.
- microSD keep in digital device and not on the shelf.
- Do not fill the card completely, there should be some free space in it.
Proper operation of SD cards will prevent half of the problems with its failures. But even if there was a loss of information on it, do not despair. Any of the above methods will help you get your photos, music, movie or other important file back. Good work!
Sometimes a flash drive, after formatting or incorrectly ejecting, starts to incorrectly display the size of the memory - for example, instead of 16 GB, only 8 GB or even less is available. There is another situation in which the declared size is initially much larger than the actual volume. Let's look at both cases to figure out how to restore the correct drive size.
Step-by-step instructions for restoring volume
To restore the actual size of the flash drive, you need to perform a low-level format. As a result, all data will be deleted from the flash drive, so first transfer the information to another medium.
You have received a completely clean media, now you need to re-partition it. This procedure is performed through the task manager:
After formatting is complete, the drive will return to its original size. If you have a flash drive from Transcend, you can restore it to its actual size using free utility Transcend Autoformat. This program independently determines the volume of the flash drive and returns its correct display.
The utility from Transcend will carry out low-level formatting, after which the actual available memory will be displayed in the properties of the flash drive.
Working with Chinese flash drives
Chinese flash drives bought on Aliexpress and other similar online sites for little money often have one hidden drawback - they real capacity significantly lower than stated. The flash drive says 16 GB, but you can read from it no more than 8 GB - the rest of the information is not actually written anywhere.
This effect is achieved by flashing the controller. If the recorded files do not exceed the actually available volume of the flash drive, then you will not understand that you have been deceived until you encounter the fact that some of the information has disappeared. But you can determine the size of the drive in advance, without bringing the matter to an unpleasant situation:
If the actual size of the drive corresponds to the declared parameter, then the test will end with the phrase "Test finished without errors". If the memory of the flash drive is actually not so voluminous, then you will see a report in which there will be two lines - “OK” and “LOST”. 
“OK” is the real memory of the flash drive, the amount that you can fill with data. "LOST" is a fake value, an empty space known only to the flashed controller. In order not to get confused, you need to restore the real volume of the drive. You can do this with a free Chinese program MyDiskFix. The utility does not have a Russian-language interface, so you will have to navigate by the screenshot.
Controller software failures.
Any flash drive has a controller chip installed. It is responsible for transferring data between the computer and flash memory. The controller is controlled by firmware. Part of the firmware is written in the memory chip (and these are mainly memory parameters, translator, various identifiers and flags, for example, the write prohibit flag). In case of various power failures, incorrect extraction and other reasons, the controller firmware fails. As a result, the controller is blocked and does not respond to requests. operating system. Also, blocking can occur due to wear of the memory chip - the appearance of defective blocks or exceeding the threshold of write cycles (then the controller itself marks the block as unused and often blocks the flash for writing). This is done so that new data is not written to bad sectors and it is only possible to read existing uncorrupted data.
When connected to a computer, such a flash drive may be recognized as " unknown device”, be in RAW format, or may be seen on the system as a zero capacity disk. When you try to access it, you may see the messages "Insert disc" or "Cannot access the disc."
Sometimes, the flash drive becomes read-only. The data is visible and readable, but when you try to create a file, erase or format, a message is displayed - "The disk is write-protected." In this case, the controller enters the data protection mode when errors are detected in the firmware or flash memory to prevent its further destruction (the NAND memory installed in the flash drive is damaged mainly when data is written).
Most recovery utilities perform a complete formatting of the memory, so if you need to save important data and not lose it forever, contact information recovery specialists. With the help of special equipment, information will be read and decrypted directly from the NAND memory chip, bypassing a failed or faulty control controller.
How to restore a flash drive.
1. You need to find out the model of the controller chip in order to find a utility to work with it. This can be done in two ways. The first is to open the case of the flash drive and see the name of the controller model printed on the chip case. If it is problematic to open the case, we use the second method. It consists in determining the model by the VID and PID codes hardcoded in the controller firmware. VID is the manufacturer ID and PID is the device ID. VID and PID are available in any USB device. These codes can be read by such programs as CheckUDisk 5.0, UsbIDCheck, ChipGenius, USBDeview, as well as operating system tools.
If VID & PID cannot be read or the values are empty, then you can try to put the controller into test mode. How to do this is described. If this does not help, there is a high probability of electrical damage to the microcircuit. In this case programmatic ways the drive can no longer be cured.
2. So, we managed to calculate VID&PID, which means there are already chances for recovery. Further, by VID & PID values, you can find the manufacturer of the flash drive and the model of the installed controller (for example, using the iFlash base). Having determined the controller, we proceed to the search for a service utility to work with it.
3. A suitable utility can be found on the manufacturer's website or in the site's utilities catalog For convenience, the utilities are sorted by controller manufacturers.
For example:
You have determined that the VID of your flash is 1005 and the PID is B113. According to the iFlash database, we find that the PHISON PS2136 controller is installed in the flash. Utility for this USB 2K REL90 controller (PS2231-UP12). And if the controller type was determined by opening the case, then we immediately go to the file directory and look for a suitable utility.
I will not describe how to work with the utilities, since there are quite a lot of utilities and the order of operation of some of them is described in the instructions that can be found in the archives with the utilities or read in the comments to them.
After the controller is restored, there is a high probability of pulling out at least some data from the memory of the flash drive. To do this, you can use the program PhotoRec.
If the data is no longer needed or the information is completely destroyed, it is recommended to test the flash memory for bad sectors. It can be done Flash programs Memory Toolkit 1.20 PRO, MyDiskTest v2.42, Victoria 4.3 Beta or Flashnul 0.99.
MicroSD recovery problem Nowadays, it is more popular than ever, and very much in demand. Flash drives often break, but half the trouble is when it just breaks, the second “bad” part is that the information on it is also lost, which is undesirable.

2. Possible problems with microSD recovery
microSD not defined
It happens that the recovery of the MicroSD card needs to be performed, but the PC simply does not see it. If this happens, there are three options to solve the problem at once.
1. If the flash drive is indicated when connected simply by a letter. Then you need to open the "disk management" program, to call it you need to enter a command in a special execution field called by a keyboard shortcut Win+R, and enter the command diskmgmt.msc. Select a flash drive, and then click "Change drive letter or path to it." After that, you will need to select any other letter of the alphabet, and save the changes.
2. Lack of drivers. In some cases, a new PC may simply not have a special driver for the media. The way out is to install them. This is done, most successfully, through offs. Website. Of course, a special Driver pack " Driver Pack Solution ". She can independently determine all connected devices to the PC and install or update drivers for it. This method is very attractive and convenient, since user actions, in this case, are minimal.
3. The last option is to simply disconnect this flash drive and connect it to another device, which will give a chance to read the files on it, or restore them using software.
The computer does not see the files on the microSD flash drive
This means that the computer does not see the flash drive as a whole, but only partially, that is, some files are there, others are not. Often users immediately come to a simple conclusion - the problem is in the flash drive and it needs to be restored, but the problems, most often, are much simpler.
The solution to this popular problem is as follows: viruses, most often Trojans, must be removed. Indeed, the Trojan can hide some or all of the files. Therefore, just turn on the USB flash drive in your PC and scan it with an antivirus.
3. MicroSD cards. Recovery from different manufacturers.
microSD transcend recovery
For such cards, manufacturers have created their own, original software to recover lost files. Called Software RecoveRx. The provided software takes into account all the features of the map, and is also able to perform a number of functions better than any other software.
