First things first

*BACKUP ALL your important data, resizing a partition (even non-destructively) always has risks especially to the data residing within it

then take a look at this thread
HFS+ resizing
(yes i know where it leads; but we're all OSS so why not lead from others shoulders-or however the saying goes)

Man, I searched the net for hours looking howto resize my hfs+, I got to some ubuntu und gentoo forums but did not find this thread.
So I just repartitioned my drive losing my MacOS installation ( I'm not missing it yet).
So thank for the link maybe the next time I try it

Trying to put YDL on my Clamshell, here is my situation:

40GB HD with OSX, I use TechToolPro and it makes an invisible/unmounted 4GB eDrive for defrag/recovery.

I used DiskStudio from same company to (non-destructively) partion HD into 20GB OSX & 13 GB YDL and retain the 4GB eDrive for OSX.

DiskStudio only lets me choose from: HFS+ journaled, HFS+ non-journaled and case sensitive/non-case sensitive HFS+ and Unix UFS.

I just tried to load YDL 5 DVD on the 13GB partition (HFS+ non-journaled). It stalled on partitioner w/ errors. Said root " / " was in use.

Is it seeing OSX as root or should I just change the 13GB partition to UFS ?

TIA

I have one more question. I heard that you need a OSX partition or the computer wont even boot. Is this true?
