Recently I have a need to format some brand new harddrives in …. FAT32 format. Needless to say, Vista doesn’t like to do that. Nor does Windows XP. But since these harddrives will be going into an old security surveillance DVR unit, they need to be in FAT32, not NTFS. I’m also taking this opportunity to upgrade the security unit from the old 30 gig harddrives to new 250 gig units.
