I am running Win 7 Pro 32 bit, AMD athalon II, 3 gig of DDR 6400, drive 1 320Gb, drive 2 1 TB. I did a partition re-size on drive one using Easeus Partition Master. I deleted partition D to enlarge partition C. when I went to recreate partition D, Easeus numbered it drive A: OOPS! Is there a way to renumber Drive A: to make it D: again. It seems that I have been able to do that in the past with either Win XP or Vista, but the pathway to that function eludes me in Win 7. I have a recent disk image that I can reinstall, but that is a last resort.
