== CLI Mode ==

In the CLI (in any mode), the command ''show disk'' will display a summary about disks on the system:
{{{

To get more information (partitions, ...), enter the DISK mode via the ''disk'' command:

{{{
hdt> disk
disk>
}}}

You can now inspect all disks via the ''show disks'' command:

You can also inspect any particular disk via the ''show disk <number>'' command (disk numbering starts at 0x80):

{{{
