[comp.sys.mac.system] SCSI Partitioning

kenw@skyler.arc.ab.ca (Ken Wallewein) (06/11/91)

Warning:  I'm going to start talking through my hat here.

I want to partition my hard drive.  It's a standard Mac drive.  I can 
partition it with the standard Mac formatter, but it refuses to let me
designate more than one partition as a Mac partition; the rest have to 
be AUX or something.  Anybody know any applicable hacks?

I want to do this to run two bootable systems (yes, one 6.x and one 7.0);
I have some "soft partitioning" software, but it just uses an INIT to 
mount a reserved area as an other pseudo-drive.  You gotta already be
booting to even mount the pseudo-drive; so much for that idea.

Is SCSI partitioning really "hard" partitioning?  How does it work?

Oh, and am I forgetting something important?

Hacks, no, but Silverlining 5.28 will do what you want, and tons more. I have
6.0.7 and 7.0 together on my drive.

I believe "hard" means at the SCSI level, "soft" means pseudo-partitions
mapped to files. Oh, if the soft partitioning software you speak of is
SUM Partition, it doesn't work properly under 7.0 anyway. Soft partitions have
their uses (well, one) but hard partitioning is so much cleaner and avoids a
lot of drawbacks associated with soft partitioning.

Ah, now that I don't know. Serious woojy-woojy magic, I expect.

You need partitioning software such as LaCie's SilverLining, which will
create true 'hard' SCSI partitions.  I think CMS sells a similar utility.
Things like SUM Partition just don't cut it (as you described).
