hi someone is selling me a powerbook, but i want to find out what the harddrive rpm speed is, they don't know what it is. Is there anyway to check using system profiler or something?

PLease may someone help, thanks.

When you open System Profiler it should say in the drives info...

It's likely to be 5400RPM, if they don't know themselves.

Yeah. In System Profiler, under Hardware->ATA, it will list the model number of the hard drive. You can click that, copy the same from the lower panel, and paste it into Google to get the specs.

[edit: yeah, what 840 said :D ]

If you are running os 10 Which I would assume you are, you can check by doing a couple of easy steps.

1. Click on the apple logo on the top left of your screen and select about this mac

2. Click on the More info button

3. Locate ATA or disks on the left pane.

You should get a readout similar to the one below

Serial-ATA Bus:


Capacity: 149.05 GB
Model: ST3160023AS
Revision: 3.05
Serial Number: xxxxxxxxxx
Removable Media: No
Detachable Drive: No
BSD Name: disk1
Protocol: ata
Unit Number: 0
Socket Type: Serial-ATA
Bay Name: "A (upper)"
OS9 Drivers: No
S.M.A.R.T. status: Verified

were it states model number copy that portion and use google to find information about that drive :)

In my case :)
