Listing Partitions and Disks with FDISK

## List All Partions and Disks #####

In order to list all partions and disks using fdisk, while root just type:

# fdisk -l

And you will get disks and partitions informations all together:

Disk /dev/sda: 32.2 GB, 32212254720 bytes
255 heads, 63 sectors/track, 3916 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 3916 31455206 fb Unknown

Disk /dev/sdb: 53.6 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/cciss/c0d0: 73.3 GB, 73372631040 bytes
255 heads, 63 sectors/track, 8920 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/cciss/c0d0p1 * 1 13 104391 83 Linux
/dev/cciss/c0d0p2 14 650 5116702+ 83 Linux
/dev/cciss/c0d0p3 651 8584 63729855 fb Unknown
/dev/cciss/c0d0p4 8585 8920 2698920 f Win95 Ext'd (LBA)

/dev/cciss/c0d0p6 8654 8907 2040223+ 83 Linux

This is quite confusing if you have multiple disks with multiple partitions, so next I'm, going to show you how to, only show the disks and then, pick a disk and then list it`s partitions



## List All Disks #####

Now I'm going to show you how to list only the disks, for that while in root just type:

# fdisk -l | grep Disk

The result shold be something like this:

Disk /dev/sdk doesn't contain a valid partition table
Disk /dev/sda: 32.2 GB, 32212254720 bytes
Disk /dev/sdb: 53.6 GB, 53687091200 bytes
Disk /dev/cciss/c0d0: 73.3 GB, 73372631040 bytes

Here you only see the harddrives and no partitions, now you can pick which hardrive you want to see the partitions. Im picking /dev/cciss/c0d0, and next i will show you only it's partitions.


## List a Disk's Partitions #####

Now listing all the partitions in one disk, for that while in root just type:

# fdisk -l /dev/cciss/c0d0

The result should be something like this:

Disk /dev/cciss/c0d0: 73.3 GB, 73372631040 bytes
255 heads, 63 sectors/track, 8920 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p3 651 8584 63729855 fb Unknown

That's all, happy listing...
