Re: Physical Disk Size

The fdisk -l does not come back with anything, i just returns to the
command prompt. The *fdisk -l* does not run at all and just says command
not found. The dmesg does not give me the disk size in the output either.
Any more ideas?

Fdisk tells you the size of the disk, as well as the partitions.

# fdisk -l

Disk /dev/sda: 72.9 GB, 72999763968 bytes
255 heads, 63 sectors/track, 8875 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14        1288    10241437+  82  Linux swap
/dev/sda3            1289        8875    60942577+  8e  Linux LVM

On the first line of output it says the disk is 72.9GB.
