Bonjour à tous,
J’ai récupérer un disque que je viens de monter dans mon PC.
Mais lorsque je fais un fdisk -l celui ci me vois trois disque 
[code]fdisk -l
Disk /dev/sda: 150.0 GB, 150039945216 bytes
255 heads, 63 sectors/track, 18241 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0000781f

/dev/sda1 * 1 17498 140547072 83 Linux
/dev/sda2 17498 18242 5974017 5 Extended
/dev/sda5 17498 18242 5974016 82 Linux swap / Solaris
Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders

Disk /dev/dm-0: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/dm-0 doesn’t contain a valid partition table
[/code]
Donc sda est mon disque système et apparemment le disque que je viens d’ajouter est vu comme sdb et dm-0…
C’est quoi ce dm-0? Je peux le supprimer? Comment?
