How to check the flash drive and microSD card for errors and test for performance? Program for checking and testing flash drives and SD cards: how to download?

A list of common problems with the work of USB flash drives and microSD cards, as well as a guide to fix them.

Problems with devices for storing information are not rare. Be it a standard computer hard drive, USB flash drive or ordinary memory card microsd, all of them are subject to both mechanical damage and software. Flash drives and memory cards today are relatively inexpensive and in the event of a breakdown they can be replaced without a special impact. But if valuable information is stored on them, which you do not want to lose at all, then you involuntarily begin to think about their restoration.

In this article, we will reveal in detail the topic of verification USB flash drives And microsd Cart For performance and errors, as well as tell you how they can be tried to restore.

Resuscitation of USB flash drives and microSD cards

Common reasons for the failure of USB flash drives and microSD cards

Physical damage to the drive

Damage to the case

Figure 1. Called reasons for the failure of USB flash drives and microSD cards

• This problem is more characteristic of standard USB flash drives. With a strong impact, the case may be damaged or the USB part is bent, which is why the computer will stop recognizing the external device. In this case, the drive is no longer subject to restoration and it can only be replaced. However, if the memory chip was not damaged when hit, you can contact specialists who, using special equipment, will restore all the data from it.

Moisture hit

• If the moisture drives enters the housing of the moisture drive, it must be thoroughly dried. The use of wet flash drives can lead to a closure and, accordingly, to the loss of information on it. It is necessary to dry it for several days in a dry warm place. Do not resort to the help of the hair dryer, because A hot flow of air can burn contacts. There is a large share of probability that after drying the drive will again work regularly. If this did not happen, then it can also be restored from it with the help of specialists.

Voltage drops

• A very common reason why not only USB drives, but also computers are out of order. Excessive or insufficient receipt of electric current can lead to blocking of contacts and a memory chip, as a result of which all information from the flash drive will be lost forever. The reason for this is often a factory marriage when the polarity of contacts is confused during assembly. The second most popular reason is non -landed sockets. The only way to prevent such a breakdown is to change the wiring in the house in time.

Logical malfunctions of the drive

Incorrect use of the drive

• Logical errors in work USB flash drives or microsd cards It is that they are physically completely working, however, when connected to the computer, the device is recognized as informed or empty. This suggests that there was a failure in the file of the drive, which could be caused by power interruptions when working with the device or the user's unfair attitude towards him. Premature extraction of a memory card or flash drive from a computer leads to damage to service tables, which is why the above problem may occur. To avoid logical errors on external drives when working in the Windows operating system, always use the function " safe extraction of the device».

Natural wear of the external drive memory

Figure 5. common reasons for the failure of USB flash drives and microSD cards

• This problem is most often associated with factory marriage or long use of the external drive. USB flash drives And microsd cards Also subject to aging. After prolonged use of the device when reading data, errors may occur, the contents of the drive can be loaded for a long time, it is incorrect to sign up archives and distort files. Often, the device can issue a notification about cRC error.
• If initially USB flash drive or microsd card It functioned normally, but after some time the described problems appeared above, the reason is the physical damage to the memory as a result of wear. The external drives use the type of memory Nandwhich has a limited number of rewriting. Constant recording and further removal of information from the drive leads to the fact that some memory cells fail. This would not be a serious problem if the recording of data on the flash drive took place evenly. However fat file system It is arranged in such a way that its system tables are rewritten after each update of files, which leads to the formation of broken sectors in the most unpleasant places.

How to check the USB flash drive and a microSD card for errors and test for working capacity Windows?

In operating systems Windows There is a standard application Check Disk, allowing to test the external drive for performance and check for errors. During the check, the application can eliminate problems in the file system USB flash drives or microsd cardsif they are not caused by physical damage. To check the device for errors, you need to do the following:

• Step 1. Connect USB flash drive or microsd card To the computer. Next, open the menu " Start"And select" " Perform". In the window opened, enter the command " cMD" and press " Enter»To launch the command line.

• Step 2. In the window opened, enter the command " chkdsk h:/f/r". Instead of " H»Write the letter under which the computer recognized your USB flash drive or microSD card. Click " Enter»To start checking the external drive.

Figure 2. How to check the USB flash drive and microSD card for errors and test for working capacity by Windows?

• Step 3. Testing the flash drive for performance and checking for the presence of errors of the file system and broken memory sectors will start. During the audit, if possible, the team will correct the mistakes found and at the end will issue a report on the work done, where the found number of damaged sectors will be indicated. To exit the command line, enter " Exit" and press " Enter».

• It often happens that to correct the file system errors USB flash drives or microsd cards standard tools Windows It may not be enough. Team " chkdsk»Makes only a superficial test. For a deep check, it is necessary to resort to specialized software, which uses original algorithms. One of the best programs for these purposes is Check Flash.
• The program is free and you can download it on the official website of the developer on this link. It is capable of working with all existing types of flash drives and memory cards, including HDD-disks, conduct a tax capacity test, measure the instant speed of reading and recording data, fully format the device, restore broken sectors and memory sections.

How to check the flash drive and a microSD card for errors and test for performance using the Check Flash program?

Important: before checking USB flash drives or microsd cards Using the program Check Flash, transfer all valuable files to another medium! In the process of checking and testing the drive, all data will be erased from it. If you are an inexperienced user and first encounter a program of this kind, it is best to seek help from a professional. The site administration is not responsible for using this software!

To check USB flash drive or microsd card Using the program Check Flash, take the following steps:

• Step 1. Download the program from the official website of the developer, remove it from the archive and run it. Further, in the program opened in the section " Type of access"Select item" As a physical device", Then select a USB flash drive from the list that you want to test. In chapter " Action"Mark the item" Read stability", And in the section" " Duration»Select" Endlessly».

• Step 2. Press the button " Start»To start checking the flash drive for errors and testing for performance. On the right side on the tab " Disk map»The course of the sectors testing process will be displayed. The working sectors will be highlighted in blue without damage, the sectors with reading errors and data are highlighted yellow and red. After the check is completed, its results can be viewed on the tab " Magazine».
