damaged files (mp3,txt , etc) on flash-drive

[Мистер Андерсон]

At mounting flash-drive 
I receive set of the damaged files on the store 
like damaged mp3's , txt , etc

First has thought that it is a problem of HAL ,
but a stop hal daemon and will mount flash driver as root
have not solved a problem all files were as are damaged

On any flash-stores which the same problem is connected through hal or through root mount
