My issue is a little different, but oh well. When I built my new rig, Vista said it needed a minimum of 15GB free space on a hard disk drive no smaller than 20GB. I have a pair of 250GB drives arranged as RAID0 and I thought it would be nice, for organizational purposes, to separate my system files from my other files. I created a partition of exactly 20GB for the operating system to load on to, unsure of whether this would be C drive or D drive, and left the rest for everything else. Well, the partition worked, but my operating system is in the normal partition leaving the 20GB I had reserved clear and free. I would like to see if I can move the operating system to the smaller partition, but if not, I guess I'd like to see if it is possible to merge the two partitions. Any ideas?
