Flashnul

Flashnull is a flash drive diagnostic software.

Usage

Removable media due to a number of features break down quite often, although not as often as hard disks. Simple defects such as "Not Detected" or "Write Errors" are detected without the use of additional programs, but diagnosing more complex faults is a very unusual task. If you have problems using your USB drive, you should not immediately format it, much less send it to the trash. Before going to extreme measures, it is worthwhile to conduct diagnostic texts with Flashnull.

Functionality

This software is compatible with almost all removable media. With the help of the software, you can conduct several tests, according to the results of which you can understand the cause that caused the malfunction:

• "Read test" - check all available sectors for accessibility;
• "Write test" - check if the sectors can be written to;
• "Save test" - check the identity of the written information and the result displayed on the screen.

In addition to these functions, the program offers lossless recording tests and saving an image of the device contents. All tests will help you find the root cause of incorrect operation of the device or its complete breakdown. In addition to analyzing removable media, the software also heals them, fixes bit sectors and other possible malfunctions. The program also allows you to create images and restore them.
