Howdy,

A recent question posted to -stable about disklabel prompted me to
play with disklable a bit.  I did this:

% disklabel ad0

And got this output:

# /dev/ad0c:
type: ESDI
disk: ad0s1
label:
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 1654
sectors/unit: 26587512
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # milliseconds
track-to-track seek: 0  # milliseconds
drivedata: 0

The point of interest was the "rpm" section.  Looking up my drive
(MAXTOR 91360U4), I see that it spins at 5400 rpm.

So I was wondering if the "rpm" section was in fact the rpm of the
disk, and if the value was important (from the disklabel perspective)?

Thanks!

Mike
