I must say that I find all this strange... I have been using my jaz
drive under both Linux and Win95 with ext2 and vfat-formatted media
with no problems other than one defective disk. 

To be honest though, I don't trust *any* storage media much. After all,
they all fail... so keep *redundant* backups is what I say. ;-)

C ya!
