Help: ADU and sharing a hard drive between a mac and 2gs

[goble@kin.on.net (David. E. Goble)]

Hi All;

I have an external 105Meg Quantum (LP105S 910109405) Ver 3.1 according
to SCSI Probe 4.3 and a IBM Seagate program.

It was partitioned (4, 32, 32, 32), formatted and intialised for my
Apple 2gs (running sys 5.0.2) with Apple II High Speed SCSI card
Utilities ver 2.0.

This has worked fawlessly. I have upgraded to system 6 and it has
still worked perfectly and the old ADU can still partition,
format/initialise the drive.

I recently got my hands on a MacSE/30 and wanted to partition and
format the drive so I can connect it to either computer as a boot
drive, by having one partition as a mac boot volume.

This is when I found a problem. I tried to repartition the drive using
the new ADU (ver1.2), after setting up the partitions and pressing the
partition button, it said; it can not partition the drive. It can
however format/initialise and zero it...

Yes, I booted from the system 6 3.5 inch boot disk and run ADU from
the system 6 tools disk. I can partition, format and intialise the
drive on my 486 and on my MacSE/30

 (The drive will not boot on the apple 2gs after being partitioned and
formatted on the MacSE/30 and having partitioned and formatted it on
the MacSE/30, I tried booting from floopies with the drive connected,
but it has a 16k partition that the 2gs wants to either eject or
initialise. I assume this is why the 2gs will not boot from the drive)

So why does the new ADU have a problem with partitioning?

Is there a way for the 2gs to ignore the 16k partition created by the
MacSE/30, so the drive can be a boot disk for the 2gs?

Also can both systems (Mac system 6/7.5.3 and 2gs system 6 be on the
drive, so that both systems will boot when the drive is connect to the
right computer?
