Pasting files to removable USB drive - 0%

Hello,

I've recently come across a problem when a user is trying to paste and sort of file to a USB drive.

Basically as soon as 'paste' option is selected on the drive, the file wizard shows the percentage which sticks at 0%. The file is only 2.5kb.

Anybody else came across this problem? The USB drive has been decrypted.

Cheers
