cfdisk
cfdisk [options] [device]
System administration command. Partition a hard disk using a full-screen display. Normally, device will be /dev/hda, /dev/hdb, /dev/sda, /dev/sdb, /dev/hdc, /dev/hdd, and so on; the default is the first device on the system. See also fdisk.

Specify the number of heads to use to format the specified device.
|

| -P format |
Display the partition table in format, which must be r (raw data), s (sector order), or t (table format). See the manpage for the meaning of the fields in the raw format, which shows what will be written by cfdisk for each partition. The sector format shows information about the sectors used by each partition. The table format shows the starting and ending head, sector, and cylinder for each partition.
