cat /proc/ide/hda/model
Then google that model number.

What on earth are you talking about?

I have doubts that there is anything that can report what you are
looking for. Spindle speed (revolutions per second) doesn't seem to be
available to hdparm, and I don't know of any value stored in the /proc
filesystem (i.e. under the /proc/ide/ide*/hd* tree) that gives you the
rpm of the drive.

No matter how you get the data, you'll need to specify /which/ drive you
are looking at. Your hda may have a different rotational speed than your
hdb, and thus there will not be a single /unqualified/ number to
indicate the value. The value will have to be qualified by the drive you
are checking.

You can read the drives id with smartctl, for example
smartctl -a /dev/hda

The you can do a look up on the manufacturer's website

Why do you care what the spindle speed is?
