it shows disk is not accessible, the volume dose not contain a recognized file
system. The most possible reason is file system errors. When there is a file system
error on your device, it will become RAW, which is not really a type of file
system but presents a problem with your drive. It typically occurs when the
file system type information is missing or inconsistent between several system
tables. Simply speaking, the file system errors that may lead to the issue in
the discussion include:
- The
file system of your storage device is not recognized by your computer
- The
file system of your device is missing
- Your
device is not correctly formatted or the file system is damaged
Such errors will happen if you have ever forcibly unplugged your external flash
drive from the computer without "Safely removing" them first.
The most effective way to fix file system-related issues is to format the
storage device. By formatting, you will assign a new file system to the device,
which will make the device usable again.
