Disaster :-(((
When I unmount the disk, the corrupted directory is written and I lose
all the files :-(
To avoid this beviour I have to try to mount the device without any
inserted disk:
[Giu@localhost Giu]$ umount /mnt/mo
I Eject the disk.
[Giu@localhost Giu]$ mount /mnt/mo
mount: /dev/sdb is not a valid block device
Now the kernel noticed the diskchange, so I reinsert it.
[Giu@localhost Giu]$ mount /mnt/mo
mount: block device /dev/sdb is write-protected, mounting read-only
(yep, I wp it to avoid losing the content (again GRRR!))
[Giu@localhost Giu]$ dir /mnt/mo
