SCSI Mac hard drives need to be non-parity. But termination is

Why, if a drive comes from one mac as a boot disk and is inserted into
another mac as a boot disk would you even consider jumpers and
termination? Same setup but the 7300's drive was swapped into a Quadra
running 7.1. works well thank you.
The 7300 has a CDROM and a hard drive (and possibly a ZIP drive) on
its internal SCSI chain. If the CDROM or ZIP drive was providing
termination, then termination is not turned on on the hard drive and
should be turned on (jumper set) before installing in an SE/30.
Depending on the model of Quadra, there could be a CDROM drive in it
as well, possibly at the end of the SCSI cable providing termination.
So just because the drive worked in a newer machine does not mean that
it is configured properly for an older machine.
John, Jeff, I was a little too quick with that one. The termination
jumper was added to the drive before installing it into the quad. Having
said that niether the disk drive or cd-rom in the 7300 where terminated.
First pointed out to me when the 7300 got its upgrade card, the first
card was a dud so it had to go to a trained monkey so he could check
things out.
However, I agree that the disk driver software which was loaded on the
disk when it as initialized could be the culprit. All of these things
need to be checked.
The leap from OS6 to OS7 is more of a driver update, once you pass OS8
things are different.
I dont recommend HD SC Setup for nuking the drive and I do mean zeroing
the drive not removing the visablable partiton and re-initalizing a new
one. I do not recommend straying from apple tools lightly nor do I
recommend leaving any other formatting tool after the job is done.
The only thing you can blame PowerComputing is building a better mac,
any disk driver is installed by default with a new OS or upgrade,
nothing to do with PowerComputing.
As I've said I have been down this road before. All the best, I'm
finished with this one.
