   That's pretty easy to do, but you're going to have to repartition it,
which will wipe any mac stuff on it now. Basically, you'll need to find
a mac partitioning program (FWB toolkit and APS Power Tools both have
been recommended, not sure if that LaCie drive comes with one. Norton
may have shipped a partitioner with their stuff, not sure), and partition
the drive as following:

- Boot partition, Max size=32MB. Should be the first partition.
- Any number of ProDOS partitions for the GS, size <= 32MB
  (Put as many or as few of these as you want; I have 5 32MB partitions
  on my 235MB drive at home)
- Any number of HFS partitions for the GS, size doesn't matter
- Mac partition, the remainder of the disk.

   Once you partition it like this, bring it over to the GS. If you have
a RamFAST, it'll recognize the partitions, and you can mount them as
you want. Format the GS partitions, and install software as normal.

   Since the GS's HFS software under System 6 seems to corrupt disks
after a while, either run a Mac disk fixer on the Mac end every once
in a while, or don't let the GS at the dedicated Mac end.

   Your system software is fine. As to scsi daisy-chaining cables,
I've seen them for $5-$20, ubt stay away from the really low end--
the worse the cable, the more chances that you'll get random scsi
errors and the like.
