I had a IIsi develop terminal hard drive trouble today. This is
usually not a problem because I always keep a couple of old SCSI
drives packed up in anti-static wrap in my parts stash. I also have a
nice G3 with a secondary (SCSI) bus in it, so I don't have to worry
about corrupted floppies and malfunctioning floppy drives.
Anyway, I tested the bad drive to make sure it was trash, pulled a
replacement out of my stash and re-formatted it because it had OS 7.5
installed. I needed it to have 7.1, so that's what I installed. I
then dropped the drive into the IIsi and turned it on. The drive
would not boot, and I was treated to a flashing question mark. I
pulled it back out of the IIsi and checked it with Tech Tools and
Diskwarrior. The drive showed up fine on the G3's desktop, and
registered no problems. I put it back in the IIsi. No success, and a
flashing question mark.
I know I reformatted correctly, into Standard format and not
Extended. I checked. I don't know why it will not boot. My floppy
drives are unreliable, because the environment in which we use them is
very dirty. I tried booting from a floppy, but that only got me a
flashing X. Again, there appears to be nothing wrong with the drive
when it is not being used as the Startup drive. I would like to
salvage it, because low volume SCSI drives are getting harder and
harder to find, and I have three machines which require them. I had
another spare, and it ended up working fine, but I didn't have to re-
format that one.
What's bothering me is that I have done this before, and not had any
problems. Is there something I need to do to "bless" the system
folder? Are there hard drives that will not boot into an OS prior to
7.5?
Check (on the G3) to see if the drive in question shows a proper System
Folder. It's possible it isn't blessed.
