fdisk -l

TestDisk is free software, and
comes with ABSOLUTELY NO WARRANTY.

Select a media (use Arrow keys, then press Enter):
>Disk /dev/sda - 750 GB / 698 GiB - WDC WD7500AZRX-00A8LB0
Disk /dev/sdb - 1000 GB / 931 GiB - TOSHIBA MK1059GSM
Disk /dev/mapper/VolGroup00-LogVol00 - 744 GB / 693 GiB - WDC WD7500AZRX-00A8LB0
Disk /dev/mapper/VolGroup00-LogVol01 - 5502 MB / 5248 MiB - WDC WD7500AZRX-00A8LB0
Disk /dev/sr0 - 734 MB / 700 MiB (RO) - HL-DT-ST DVDRAM GH24NS90

Disk /dev/mapper/VolGroup00-LogVol00 - 744 GB / 693 GiB - WDC WD7500AZRX-00A8LB0

Please select the partition table type, press Enter when done.
[Intel ] Intel/PC partition
[EFI GPT] EFI GPT partition map (Mac i386, some x86_64...)
[Humax ] Humax partition table
[Mac ] Apple partition map
>[None ] Non partitioned media
[Sun ] Sun Solaris partition
[XBox ] XBox partition
[Return ] Return to disk selection


Hint: None partition table type has been detected.
Note: Do NOT select 'None' for media with only a single partition. It's very
rare for a drive to be 'Non-partitioned'.
