Well, I have of course tried this (not in fstab, but in
sudo mount -t ext3 /dev/ide/host0/bus1/target0/lun0/disc /mnt/ext2/

My ZIP 250 isn't shown at all correctly: all infos are the one from my
first HD hda... even if I call /dev/hdc or
/dev/ide/host0/bus1/target0/lun0/disc...

If that's could help, some more infos:

Gives the same...

Thanks you very much,
