SCSI hard-drive partition questions

[Dennis Jenkins <dennis@usb.com>]

Hello all,
	I'm having difficulty getting my hard-drive on my IIgs to be recognized
when I remove it from the IIgs and attach it to my Mac LC-II.  For
anyone to help me, I should start at the beginning:

0) I won an ebay auction for an Apple SCSI card.
1) I took a 40M Original Apple HD out of a spare mac and placed it in a
SCSI enclosure.
2) I used Mac software (Apple HD SC Setup) to partition the drive:  32M
prodos and 8M HFS.
  The Mac recognized everything just fine.  I was able to copy lots of
files into my ProDOS
  partition using the Mac's Finder.
3) My SCSI card arrived, I plugged it into my IIgs.
4) I attached the 40M HD to my IIgs.
5) The computer failed to boot from the HD, so I booted prodos from a
800K floppy.
6) ProDOS did not recognize the partitions.  Ug.
7) I used 'filer' for format the drive.
8) I copied my files back to the drive, one at a time, using 'filer'. 
(that sucks)
9) I can boot from my HD.  Yippie!
10) 2 weeks later I decide that filer sucks, and since GS/OS doesn't
like my SCSI rom,
  I can't run GS/OS's finder.  So I attach the drive to my Mac.
11) The mac won't recognize it.

	I suspect that 'filer' formatted the first 32M of the device as a raw
prodos device.  Ie, 
no partition table, no SCSI v4.3 driver partition, just 65534 blocks of
prodos followed
by 16386 blocks of junk.  (yes, I'm 2 blocks short of a full 32M.  I
have no idea why filer did that.)

	I have never run the official apple II SCSI utilities on the device
(but I did download them.  I will play with them soon).

	I want to be able to attach the HD to the IIgs or the Mac LC-II and
have both computers recognize both the ProDOS and HFS partitions.  (I
realize that until I get my ROM upgraded, I can't run GS/OS, hence no
IIgs access to HFS).  However, the Mac wants a partition table and the
IIgs SCSI card (rom ver B) appears to hate partition tables (I will
check the device later to see if it really does have a partition table).

	I don't mind reformatting the whole thing, but I will need to back it
up first.  I can probably attach it to my Linux box and use 'dd' to copy
off the sectors that form the ProDOS partition.  I can then repartition
the device so that the ProDOS partition has exactly 65534 blocks, and
then DD the prodos filesystem back to the HD.)  If that doesn't work,
I'll ShrinkIt everything that I currently have (about 3M of stuff) to
800K floppies.

	Any ideas, thoughts, suggestions, etc... ?
