How can I see all the physical hard drives on my Ubuntu system — regardless of whether they're mounted — as well as their partition info, sizes, &c.? I have three physical drives, but only one seems to be mounted. I'd like to mount the other ones too, as I have some data on them.

What gets mounted is the filesystem on a partition, which might cover a whole disk, but I wouldn't call it mounting a drive. – user unknown Jul 22 '11 at 13:41

I've used fdisk -l to solve this problem.

"fdisk -l | grep sd" should reduce some clutter if the drives are /dev/sdx etc – Andy Lee Robinson Jul 26 '11 at 3:27

You may also want to try the cfdisk command. I use it in conjunction with fdisk and I always find that it gives you a clearer view of my drives and partitions than fdisk.

Just be careful, though, because you can use it to break your partition table.
