[comp.sys.mac] Untapped Disk Potential

pff@beach.cis.ufl.edu (Pablo Fernicola) (12/07/89)

MacWorld's January issue has a letter on page 247 that talks about putting
unused hard disk space to use.

When I try to follow the procedure outlined there, using HD SC Setup utility,
the "Partition" button is grayed out.  A friend with the same setup (but
running system 6.02, I am running 6.03) has no problem doing it.  As a matter
of fact he found out that he has 1 more Meg that he can put to good use 
(installing Colony again :-)).

Any clues?

I have a SE with a 20 Meg internal hard disk.
System 6.03  and HD SC Setup version 2.0.
Inits: Gatekeeper, boomerang, Logout.

Note: I tried booting off the System disk, but that didn't help.

Your hard disk was probably formatted and initialized using an older version
of HD SC Setup, which had an older disk-driver.  In order to use the
partitioning capabilities of the new HD SC Setup, you must install the
new disk driver contained in the version of HD SC Setup which came with
System 6.0.3.  I believe that this new driver requires more space in the
driver-partition than the old one did... or requires a somewhat more
complex partition-table structure.

In any event... in order to do what you want to do, you are going to need
to reformat your disk, using the new version of HD SC Setup.  This will
install the new driver, and create the new-style partition table.
You'll then be able to click the Partition button, delete your existing
Mac HFS partition (the default-sized one), and create a new Mac HFS
partition using all of the available space.

The usual warning apply: back up your disk before doing this (twice, if
possible, to two different kinds of medium).  Use ONLY file-by-file
backups, *not* image-dump backups!
