well yes.. thanks Kels, that's the purpose of this. all my data and audio will be on a 300gb SCSI RAID1 array, so that's protected. if the O/S on (C:\) gets fuct, does it matter if the major Programs are on (D:\).. or would I have to re-install those anyway? would a re-install (or repair) to "C" break all the registry ties to "D"? the that's why I post this Q.. i've heard differing opinions. maybe separating is good for making backup images only? just want to know all the reasons for doing this. I hope to get other comments. do most of you who have fast systems keep the Program Files folder on it's own partition? .. or anything else for that matter that's included in the XP install? ~ TIA

from a 36gb SCSI drive.. I thought to install XP into a 25gb partition and keep the C:\Program Files folder for what needs to go there. then create another 10gb part as D:\Program Files for major apps. i've searched a bit and found different opinions. besides Defrag efficiency, is there any good reason to have these separate O/S partitions in a new build? the Paging file will set itself as necessary and i've read the Documents and Settings should also stay in place.
