Stupid Linux HDD question.

[theweaselking]

Is there an easy way to have the machine tell me which hard disks it can see, and what their device names/numbers are, even though they might be unmounted or unformatted? An equivalent to Windows' Disk Management?

Debian 4 in the specific case, but a general would also be nice.

EDIT: Hmm, /dev/disk/by-id/ is a veeeeeery interesting folder. Will that show disks that aren't partitioned, though?
