If you are looking for a 3 1/2" desktop hard drive I have two Quantum Fireball Plus LM 30 GB drives. (GTLA: LM30A011-01-A). They are 7,200 RPM, 2 GB buffer and 8.5 ms average seek time. Full specificatiions and support information can be found at:

I just removed them from a Snap Server and replaced then with 120 GB drives. Way too much music to store and backup! They worked fine in the Snap and I have used the other two I had on my sister's Win2000 machine as backup drives.
I had not thought yet about a price but if you are interested please make me an offer for one or both. I am in the San Francisco Bay area and can ship via FedEx Ground for reasonably priced, insured transport.
Thanks,
Michael
