How do I find out what hard drives are attached to a Linux box? I'm hoping for a single command that can give me a nice list of all ATA/SCSI/etc drives.
I've catted /proc/partitions in the past to do this, but I wonder if that still works if there's a drive with no partitions on it.
sudo lshw -class diskgives you everything but the mount point

When I run:
# lsblk
it returns tree disk-partition with mountpoints (for those partitions that have):

lsblk works nicely with watch to see when drives are attached, removed, or mounted. This is my currently favorite format: watch lsblk -o tran,name,model,fstype,label,mountpoints,fssize,fsavail,fsused,fsuse%. Here's a tutorial about lsblk that also explains how to define which information to show about drives and their partitions.

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.
/proc/diskstats will have stats on all your extant drives, whether or not they have partitions on them.
cat /proc/partitions Is working even if there is no partition defined for disk.
My favorite is lsblk which shows very good detail about disks and partitions, and where they mounted. Also file -s /dev/sda can give you simple information too.
I like:
lshw -class disk
which lists all disks and storage controllers in the system.
# fdisk -l | grep Disk
is used to display list of harddisk on server
Not sure if it changed at some point, but using sudo lshw -class disk did not work for me. On my system, Ubuntu 17.10, I needed to use the storage class:
sudo lshw -class storage
Alternatively, you can use duf that conveniently groups devices by their type and shows disk usage per default.
