How to I use an ex-Apple II SCSI harddisk on Mac?

[Lim <idl6@pacific.net.sg>]

I just finish transfer all needed Apple IIGS software from the GS's
harddisk to Mac (running GS emulator).

Now, can I:

- Use that external SCSI harddisk on Mac? If yes, how? I tried Apple
harddisk setup and it say it does not recognize the harddisk (although
it shows it) and refuse to format it.

- The harddisk is 120MB and have 4 ProDOS partitions, can I retain
the first partition in ProDOS and format the rest with HFS and share
with Mac? If yes, how?

Thanks.
