I've recently purchased a 180GB IBM DeskStar hard disk and went about installing this as my main drive with XP Home. However, when I installed XP it only recognized the size as 130 gigs when it is actually 180.... I've since used IBM DiskManager to try and install it to it's full potential using that but it seems to only want to create a Fat 32 partition of the full capacity and not an NTFS like I wanted. Even then I'm not sure if it will work as I haven't had a chance to try it yet.
I know about this issue with motherboards that don't support 48-bit LBA addressing which is needed to recognize drives over 137 gigs but the last BIOS update for my mobo which I installed some time back supposedly fixed this issue. I'm using the Asus A7A266-E w/ ALi Magik chipset.
