Plugged Parallel into SCSI hard drive

Recommended Posts

I accidentally thought that a zip drive was scsi but it was parallel and i plugged it into my scsi external hard drive which was plugged into my mac plus!!! And now it wont read or detect the disk. I tested it on another mac and it didn't detect it either. My question is did the enclosure, drive, or Macintosh break? Can i get a new scsi drive and plug it into the enclosure?

Plugging parallel devices into the SCSI port will short out some data lines on the SCSI bus and fry your SCSI controller and everything else that is connected to the SCSI chain at that moment.

So you might need a new drive and a new SCSI chip on your logicboard.

 

If the drive does not show up on another Mac it is most probably toast.

There usually is no logic inside those enclosures that could break.

 

The drive itself and the Mac can break though. I wohld get another drive and check if the Plus can see it. If it doesn’t then your logicboard needs repair as well.
