TjJazer,

Try rebooting the SE/30 off of the floppy drive. Then run Disk First Aid or Apple SC HD Setup or some type of equivalent hard drive utility program. We just need to check if whether in fact it is the SCSI bus that is the problem or whether it is just a hard drive issue. If you can see the hard drive in the utility program but not mount it on the desktop, then it is the hard drive that is the problem, not the SCSI bus.

Are you able to boot off an external SCSI storage device plugged into the back of the SE/30? If you can, then I would say you may just have a bad Bourns network filter, located at RP2 on the logic board. Remove that and the internal SCSI should fire right up; although, obviously, when you remove the Bourns chip you disable use of external SCSI connector.

Give this a try and report back with results.
