I just got a WD 160 gig (8meg cache 7200 rpm) HD to replace my old 60 gig I used as my D: storage drive. I am wondering if it is better to use the 160 gig as my main C: and make my current C: 120 gig (8meg cache 7200 rpm) HD the storage drive? I am running NTFS with WinXP and SP1 and am looking for the least amount of problems since I like to reinstall Windows every few months to clean out all the junk. I did notice that when I used the WD HD Install CD in Dos, it put a limit on the HD at 137 gig till I got into Windows and ran the utility again to regain the full 160 gig. Any info or insights would be appreciated. Thanks in advance.
