Okay, so basically you just need to figure out how to make your
Mac partition smaller, so that there will be room on the disk
for UNIX partitions. Most partitioning programs (with the notable
exception of Apple HD SC Setup--thumbs down on it) can change
the sizes of Mac partitions--the only nontrivial thing about
that is that you have to tell the filesystem data structures
that they now have less space to work with. Most programs do this
automatically when you change the size of a Mac partition, so you
won't need to worry about it.
The problem with this is that the Mac filesystem can get like
a piece of swiss cheese--bits of files all over and holes all
over. So even though the Finder says you have 300 megs free,
that 300 megs may be spread out over your disk, and there may
not be very much free at the end of the partition, where the
partitioning program will take the space away. The way to fix
this is to run a program that rearranges your files so that
they're clumped together at the start of the partition. Most
programs which tout their ability to "defragment" Mac volumes
can do this--although you may have to enable a special
option. After you have as much space as you need to take off
free at the end of the partition, you can use the partitioning
software to reduce the size.
Appendix:
(Partitioning software)
best: FWB Hard Disk Toolkit (HDT)
Personal edition US$60, or full edition US$155
Notes: You can pretty much do anything with this
package; it's powerful, easy to use, and
won't restrict you from doing whatever you
want to. It has extensive formatting and bad
block handling. The full edition can do RAID
and encryption, and lots of low-level stuff.
second: Alliance Power Tools
Free:
ftp://jagubox.gsfc.nasa.gov/pub/mac/APS273.sit.hqx
ftp://dunkin.Princeton.EDU//pub/jagubox/mac/APS273.sit.hqx
Notes: This is good, for a free program. It's a bit
pushy: it thinks it knows better than you what
partitions you need. Don't let it fool you:
all that eschatology crap is unnecessary.
third: Silverlining
Proprietary software from LaCie, you can swipe it from
someone who has it.
Notes: Very bad interface, but you can still get stuff
done. Includes a rudimentary defragmenter (see
below) so this may be the best bet if you don't
have one already. Overall, though, I've been
much happier since I switched to HDT!
worst: Apple HD SC Setup
Comes on the Disk Tools OS distribution disk
Notes: Very bad--can't do even a tenth of the things
any decent partitioner should. I'm not certain
on this, but I think it messes up when you
try to reduce the size of a Mac partition--
and I've personally experienced loss of data
from it. If you must use it, there is a hack
someplace on the net that allows you to use it
with non-Apple drives, and another hack that
allows you to create multiple Mac partitions
on the same device--something that all of the
other programs come being able to do.
(Defragmenting software)
best: Norton Speed Disk
Comes with Norton Utilities, US$100
Notes: I like this program a lot. I've never lost
data with it--it's programmed very defensively.
Plus, along with it you get a very good set
of backup, disk editing, and file system check
utilities. Version 3.0 had problems; make sure
you get 3.1, or else go back to 2.0, which
also was rock-solid. I, personally, use 2.0...
second: MacTools Optimizer
Comes with MacTools, US$119
Notes: This is a decent program. MacTools and Norton
Utilities pretty much serve the same purpose.
third: SilverLining
(see above)
Notes:
If you want to go real cheapie, the folks at
LaCie included a rudimentary disk defragmenter
in their partitioning package. It works for
its intended purpose, but that's all I can say.
Hope I've helped! I'd like to see a section on this in the FAQ; it's
confusing considering that Apple put such a dumb program in with their
OS.
