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
*-cdrom

*-disk:1
description: ATA Disk

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
disk:
/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

EDIT:
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):
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

+-sda1 8:1 0 500M 0 part /boot

+-sdf2 8:82 0 2.7T 0 part
Solution 5:
/proc/diskstats will have stats on all your extant drives, whether or not they have partitions on them.
