Hello

 

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?

Does another, similar, flash drive do the same thing?

Nope, only that device shows that particular behaviour

Sounds like this drive is failing/has failed. Since you say you can access it and read files on it copy any data off it and replace it with a new memory stick.

I am going to be away until about the 22nd October. Time on-line will be reduced and my internet access may be limited. PMs may not be replied to as quickly as normal !
