In fact I'm using VL 5.8, and it's rather easy to imagine someone didn't unmount the disks in a proper way.
BTW, on a mp3 stick it's said there are 0 kb available, but on windows it says around 350 mb. On an external Hd I've got 19 mb available on Linux and a dozen GBs on windows. On another external hd I read 11 mb on Linux and about 450 on windows.
IS there another way to solve this problem (something different from formatting the disks on a windows machine, wich is what you suggested.. if I didn't misunderstand)?
Thanks in adv.
