Disk utility initialising almost every SCSI hard disk for SSW 7.

Useful if you wanted to format a non Apple drive.

Architecture: 68k

Apple HD SC Setup v7.3.5, can partition SCSI hard drives and format them for Mac (HFS), Unix (A/UX) and ProDOS systems.

Limitations: Predates HFS+, therefore cannot format drives as such.

For instructions or hints on patching "Drive Setup" to format unsupported ATA & SCSI drives.

Note: Patching Drive Setup requires using ResEdit.

Reverse engineers and localization enthusiasts, the patch change an octet (it sometimes is enough):
wfwr 67 0x0000: 00 -> FF

EDIT: this was already explained here

Both of these failed for me under MacOS 8.6

I do not recommend that anyone use this in a Mac OS beyond 7.6.1 - This formatting tool predates HFS+ (which it cannot do) and for Mac OS's from 8.1 on and with much larger capacity hard drives that have emerged since 1995, HFS+ is pretty much the only way to go.

For larger capacity SCSI drives of say 4GB and larger; If they are unsupported and cannot be initialized or formatted by Apple's Drive Setup (assuming using a classic Mac OS here), then its possible to patch Drive Setup too. That way you can get an HFS+ formatted unsupported hard drive with Apple drivers. - Or, use any other formatting tool, or OS X's Drive Utility, etc...

That said. For earlier 68k Macs running Systems from 7.0 through 7.6x, I have had very good results with the patched HD SC Setup tool, when formatting unsupported SCSI drives. No failures to formatting so far. Not that I've used this with every unsupported SCSI hard drive on the planet to come up with some kind of statistical error rate...

Anecdotal evidence suggests that this is successful in about 80% of operations while a third party SCSI partitioner Lido worked in well over 95%. Both of these failed for me under MacOS 8.6 in a B&W GB with a drive attached to an Adaptec card. I managed to get the drive sliced and mounted with Anubis 3.1.

Depending upon your setup, you might have to try a few of the old SCSI utilities before you find one that works.

If I'm not mistaken this was succeeded by drive setup, either way I found this file's original page here for the sake of completeness.

Fixed the mistyping.
