I have been scavenging around my school and come across two powermacs, 5400/200 models. I've got one to work, but the other won't recognize hard drive. The computer gets stuck on the floppy with question mark. I have been able to get passed this with disk warrior, norton, and the system disk. However nothing recognizes the drive(including Apple disk utilities). I know a couple of 5400/200 have already had their HD's replaced in the building. Trying to reset the pram has been unsuccessful. Is there anything I can do before recognizing the drive dead? Thanks
