CiderPress can read and write files and whole partitions directly from
a SCSI hard drive connected to a PC.  Extracted partitions are just .PO
hard drive files, which KEGS will recognize and use.  (It also makes
Apple II hard drive backups a whole lot easier.)

The idea of booting from a floppy is a good one, though I don't know if the
standard GS/OS boot disk has SCSI drivers installed.  You know the drive
is good, and you're able to read *some* data, which means something has
gotten flaky.  I've seen this happen with bad cables and bad SCSI
termination.  Do you use the same cable and terminators on the PC side
that you do on the Apple II side?

In any event, swapping out the cable is cheaper and easier than anything
else you might try.  Make sure the terminator is snug.
