Every time I try to boot from my LC 520's internal SCSI hard drive bay, it hangs. My external SCSI drive never fails to fully boot, however. I have also swapped the drives and the same thing happens, so I'm led to believe it's the internal hard drive bay itself. All pins are intact, unbent and clean. I have tested both drives on numerous other systems, both 68k and PowerPC, and they work fine every time. Can this be a logic board issue? I've never heard of the internal bay not working while the external does, especially if they're on the same bus. Could it be a capacitor issue? They are long overdue for replacement, despite a lack of leakage.

I’d check termination on the drive. Some have a place for physical termination packs on the circuit board of the drives. If that looks good, have you recapped the 520’s logic board yet? If not, that may be a contributing factor.
