You really want a partition that big anyway? The cluster size gets very large (32k?) I think. How about chopping it up a bit? I know everyone has their own ideas about partitioning. I just put in a 30 gig, and did this: C: 3 gig (windows), D: 13 gig (programs), E: 13 gig (data). The reason is that the fastest part of the drive is the outer tracks. With Windows and the swap living there, it will always use the fastest part. Programs are next in the D drive, with bulk storage going at the end in the E drive. I have 4k clusters in c: and 8k in D and E which are much more efficient. An additional benefit is it takes less time to defrag. I usually just do the C and D.
