I have a Sandisk Ultra USB Flash Drive (USB 3.0), and one day, when plugging it into a computer at my school, it started unmounting itself.
It's more like you can plug it in a Windows computer, and you get to access the files for a shor time before unmounting itself.
The drive shows this behaviors in these operating systems:
Windows (any version): can access, read and write, but ends up unmounting itself, write operations don't seem to take any effect
Mac OS X: hangs the computer until unplugged
Linux: (currently untested)
I've tried running chkdsk, formatting (both low-level and with windows tools) the drive, and always displays the same odd behavior (plus, the content inside always remains the same). What can be done to fix the problem?
