I tried all your solutions but didn't work.
I don't understand why i can erase with OS 9 drivers on my usb key and not on HDD.
This is what happens sometimes when you try to troubleshoot on a forum. What would take 5 minutes to go and test in person takes days of back and forth.
OK… Let's try some deductive logic:
You have TWO internal HDDs installed and a USB thumb drive.
We know you can get the OS9 drivers option showing on the thumb drive.
You cannot get it on at least ONE internal HDD.
SO,
How about the other internal HDD? If you choose "Erase" on the other one (you don't have to actually erase it of course) does the OS9 option appear there?
If YES, then you have one drive that won't cooperate and the problem is specific to that HDD only. So… Do a complete erase of that drive (one-pass is enough) then try to initialize it again. If it now works, there was something about
the formatting (who knows what?) but it's fixed. If it still won't cooperate, you may have to replace it.
If NO, and neither drive will allow OS9 drivers, then it's a different issue entirely. So… Check the connections to the HDDs and the drive settings. In an MDD, the drives must be set to "cable select" rather than "master"
and/or "slave". This is probably NOT the problem because I don't think they would even show up properly in the profiler and maybe
not function at all if set incorrectly, but who knows? Maybe they can and do. It
does mean that there's something about both
identical drives that the OS doesn't like, we're one step closer to the answer, and we go from there.
Which is it? Holler back.
