Hard drive seems to have failed and I am trying to find out what models will replace it. Does the rpm have to match? It currently has a Hitachi 20GB 1,2.5" format,9.5 mm, ATA/IDE and I would like to replace with at least a 40GB drive but am finding conflicting information as to what will replace it, any ideas?
