I obtained three SCSI harddisks Seagate Barracuda, modelnumbers ST32xxxN. From the labels attached to it I think they come from Compaq servers. None of them work:
1. Starts spinning and stops after a few seconds.
2. Starts spinning, gives a "clunk" and then stops
3. Spins, but is not recognized in HDToolbox.
Tested in an A590.
Can I throw these in the bin?
