The SE is Mac Plus speed. It likely expects the hard drive to be formatted at a 3:1 ratio (3 spins for one read). The SE/30 has a 16Mhz. bus and its hard drive is likely formatted at a 1:1 ratio.
If stiction (freeze-up) is not the issue and you can hear the drive spinning, it may be the wrong OS, version, bad platters, motherboard SCSI chip, SCSI cable.... Time to crack it open and have a look.

I thought it was the hard drive so I replaced it with one from a mac se 30 but it still does not show the hard drive. Is there something I have to do to show the hard drive? It boots off its floppy right now. -- -- ----- You received this message because you are a member of the Vintage Macs group.
