How can I find out what hard disks are attached to a Linux box?

Solution 1:

sudo lshw -class disk

gives you everything but the mount point

sudo lshw -class disk -html

Solution 2:

fdisk -l

Solution 3:

An alternative to lshw:

hwinfo --disk 

Also has '--short' option, if you're only interested in the /dev and model name and not all the details.

hal9k:~ # hwinfo --disk --short
  /dev/sda             Hitachi HDT72502
  /dev/sdb             Generic USB SD Reader
  /dev/sdc             Generic USB CF Reader
  /dev/sdd             Generic USB SM Reader
  /dev/sde             Generic USB MS Reader

Long version gives you more details then lshw:

hal9k:~ # hwinfo --disk

As for the packages availability. I'm using OpenSUSE 11.1. hwinfo is in the standard repository, while lshw is only available from unofficial one.

Solution 4:

When I run:

# lsblk

it returns tree disk-partition with mountpoints (for those partitions that have):

Solution 5:

/proc/diskstats will have stats on all your extant drives, whether or not they have partitions on them.
