Fix SD/USB Memory Tool

It happens that the SD card or USB flash drive work, but the files on them after recording are obtained "broken", do not open or have a partial loss of data. The rest of the files are OK.

The utility checks the SD card and USB flash memory for writing and reading files in 1Mb chunks.

Takes up all available space files, then reads them and checks the loss of data. If there are broken areas on the disk, such files remain and are not deleted.

After working off the utility, such broken files occupy all non-working space and the disk can be used without fear of losing the data being written.

Do not delete the created '_BadFiles' folder if problems are detected.

You can make it invisible and read-only, that would not interfere.

Before running the utility, clean the disk completely, otherwise the scan will take place only throughout the free space.

For Android 5+, configure access to memory for the utility, and mount the SD\USB memory itself for recording (W/R).

The running time of the utility depends on the speed of memory and may take several hours. Recharge the battery before use.

PS. If the disk does not work at all or is write-protected, the utility does not help! Salvation shall be working on the failing device. Please do not waste time installing the program.
