I have a few questions, I've never understood this completely. I've got an iMac powerPC g4. Ideally, I want to use this primarily for audio programs. At one point I'd heard it was a good idea to partition the internal drive, which I did. It's never worked out quite as well as I thought, there's really no advantage to having seperate drives; so I'm ready to ditch it. Here are my questions: 1. How do I un-partition?? can't find the option in disk utility, nor in a clean OS install. (disk utility, btw, also doesn't seem to let you change the size of the partition either...?) 2. OS upgrades... I partitioned it when I did a clean re-install of OS 10.3.9. I've since been trying to upgrade to 10.4.6 - have tried doing a clean re-install twice. I'm having some software glitches with my music app's in 10.4.6, just wondering if it could be related to the partition. Can a partition affect the way app's are installed/accessed? (all app's are on the startup disk) 3. Out of curiosity, I assume that the partitioned section remains at OS10.3.9; while the startup portion gets upgraded to 10.4.6 -- is that correct? So should one do an OS re-install on EACH portion of a partitioned drive, or will it figure itself out? ===== Will appreciate any info from wiser folks out there!
