With Easter and all, I wasn't able to get my hands on the machine until just now.
I took it apart to see what hard drive I need to get for it, and it turns out that the machine is running an EIDE Western Digital Protege WD800 80GB
Would it be possible to run this hard drive with another, newer one? The Protege runs at 5400 RPM, would I be able to run a 7200RPM slave? I'll try to talk him into buying a pair of new hard drives, since it's probably not a good idea to buy old technology.
His motherboard is a
P4M80-40
As you can see it supports SATA, (although I'm not exactly sure what bandwidth) so it might be a good idea to go with that. He doesn't download a whole lot, so I think a pair of 80GB sata HDs would be more than sufficient.
I'd really appreciate any advice guys, I'm still undecided as to what I'm going to do.
