Disks information

CLI Mode

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

hdt> show disk                                                                  
DISK 0x80:

DISK 0x81:

         Host bus: ISA, Interface type: ATA

         Host bus: ISA, Interface type: ATA                                     

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:

disk> show disks

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

disk> show disk 0x81
