It's an Apple II SCSI card, of which I just the found the manual here. But according to that manual, I have to use software provided with the SCSI peripheral to format and partition it.

The disk I intended to use is an old standard 200 Mb formatted in HFS I found a long time ago.

Can you advise me some third-party formatting software?

And from what I read in the card's manual, I could only have four 32 Mb volumes. It seems to mean that my 200 Mb disk will soon become a 128 Mb, but hat's no big deal!
