I am trying to install some replacement HDs into some OLD 030 macs and I am encountering some frustrating issues.
First, Apple Drive Setup doesn't support these drives because they come from weird and bizarre computers unknown (at least two HDs are listed as "Compaq" even though they are clearly made by IBM or Seagate.
Second, I cannot get any of them to mount normally.
What program should I use in OS9 to update the drivers and be bootable? I have the drives on the SCSI bus in a 7300.
Does anyone know if I will be able to actually install OS 7.6. on them and get them running in an LCIII or Performa 525? My first attempt was unsuccessful (it was not recognized).
I want the machine to think they are Apple drives. Is that possible?
I realize I am about 10 years too late, but you gotta have a hobby.

I'm a little fuzzy on the details but you might look for LaCie's Silverlining program. ADS had a tool as well, but I forget the name of it.
Good luck. :-)

You're not too late. There are still plenty of Mac SCSI guys around.
It's amazing how quick you can google up something if you remember what you're looking for. This patch isn't guaranteed, but I've had good luck with it.
Download Apple's HD SC Setup 7.3.5
Then read this page.

Downloading now. I'll hack it this evening and post back.
A question regarding the old LCIII: Does the hard drive need to be terminated or is it done on the mobo? There is only room for one SCSI drive in the system and it doesn't have a floppy. I also have a LC525 with a 2X CD rom but it is missing the CD caddy. It also takes only one HD.

If it's the last device on the SCSI chain, it needs to be terminated. Usually you push a jumper onto two pins on the front of the drive. The drive manufacturer's site will have the details for that model if the label doesn't.
If the drive is beyond hope, then you can Terminate it various other ways.

Success! I got a copy of Apple SC HD Setup patched to read any drive, initialized, partitioned, updated the driver, then installed the OS and got it working.
I did some reading up on SCSI systems and assumed that since the LCIII had no other SCSI devices (no CD-ROM) that the SCSI chain was terminated on one end (the mobo) and therefore must be terminated on the other (the HD). It worked first time.
I have two more drives to prep, but it looks like this lesson about classic Macs has concluded successfully. I thank you all for your help.
