That depends on if you mind formatting it.

Anytime you change the partitions of a mac drive, you have to reformat it (through disk utility)

If you don't mind doing that then boot to your OS X disk, from the apple menu select 'open disk utilty'.

select the hard drive (should say something like '57.4 GB Maxtor 96052' It obviously won't be the same information, but formated as such)

Next, select the 'partition' tab on the right. Where it says 'Volume Scheme' select '1 Partition' from the pop-up menu and click on 'Partition' Button.

quit out of disk utility and reinstall.

There are other non-destructve partition tools for the mac, but i don't recommend them as they have yet to really prove themselves.

iPartition from Coriolis Systems will easily enable you to remove partitions without reformatting your drive. It's relatively inexpensive and easy to use. Check it out here:

You should make it standard practice to back up important files regularly, and particularly before doing any major disk operations like repartitioning.

thank you for the info about that software ... I did not mention in my original question, but I was in fact looking for a utility that would allow me to resize partitions without losing data.
