i'm going to partition my HD as soon as i get 10.2. i'm going to make seperate partitions for applications, startup disk, documents and an OS 9 startup disk. oh, and i'll also make a temporary/downlads partiton for stuff i get from the net, etc. i was just wondering what size should i make the OS X startup disk? would 500 or 600MB be enough? and i'm guessing that the OS 9 partition would only need to be about 2GB (i still use a couple of OS 9 apps). i just checked my applications folder the other day and the total was about 7GB. but a heap of that is freeware/shareware stuff that i don't really need. so i'm thinking about making the applications partition about 5GB. is this big enough? i'll have Macromedia Studio, Photoshop, Illustrator, Maya, InDesign, Final Cut Pro, After Effects and a couple of other apps. and i also want to make a partition just for a scratch disk for Photoshop. if i make a 2GB temporary/downlads partition, would this be suitable for use as a scratch disk as well? so far this is what i'm planning for the partitions (BTW i've got a 30GB HD): startup disk (OS X): 600MB (only for system stuff, not for saving documents etc) startup disk (OS 9): 2GB (i still need Quark and some other apps) applications: 6GB (just for all of my apps) temp/downloads: 2GB (just for temp & downlods, also for a Photoshop scratch disk) Documents: 19.4GB (for all my mp3s, and work, etc.) i guess that the actual formatted size will be less than 30GB, so the documents partition will be a bit less. so does this sound like a good idea for partitions? are there any other partitions that it would be good to have? if anyone has any comments or suggestions, don't be shy. i need as much help with this as possible.
