Can anyone help - I have acquired a couple of old IBM 500Meg SCSI hard
drives which I would like to to be able to format properly to use HFS+
My internal Hard drive is only a 700Meg but with HFS+ the block size
comes out at 2K, but these External IBM ones after HFS+'ing have block
sizes of 4K.  I would have expected them to be 2k or even smaller with
HFS+.  I have only the supplied "Spirit Utilities" disk formatting
utility which is dated 1993 and cannot trace a newer version with which
to reformat the disks.  It would be nice to be able to use Apples own
formatter but it  recognises these disks as never having been an
"orginal fit" to an Mac model and refuses to do a format on them.

I read somewhere once that you can with some jiggery-pokery hack Apples
own formatter so it enables formatting of any SCSI disk and not just the
ones Apple has at some time in the past fitted to one mac or another.

Question is:
Can someone tell me how to do this hack, or alternatively tell me where
I might find another utility which CAN format my disks properly, but
which either a) is shareware (or cheap) or b) is an update to Spirit Utilities

My disks are IBM models DSAS-3540
