The scsi termination may have been screwed up and that may have caused
my problems in the first place. but the scsi chain is now back in the
state it has worked in for 3 years.

I did some more examination. The "problem" hard drive is being seen as
one device by GS/OS but the data on it is actually in 8 partitions.

I can examine the unmounted device through ProSel's block editor and at
device 5 I can see data is on the disk. The first few blocks on the
disk have apple_partition_map, apple_PRODOS, and apple_free data on
them. I can see the prodos boot blocks on the disk starting at block
$0020. I think the partition data was messed up but I have no
information about Apple partition blocks or how the ramfast card writes
partition data.

Is there any way to fix the partition map without repartitioning and
loosing the data on the drive?
