Thanks for all the suggestions. I think I'll just take both systems home to work on. I don't have an CD / DVDs here which I plan to correct. I'll make recovery disks and try to recover.
I'll also use my clone duplicator to clone both drives to a couple new WD green 2TB drives and then retire these as backups.
I was just hoping for an easy way to reset the drive but windows isn't real friendly for that type of thing.
As democracy is perfected, the office of president represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron. -HL Mencken 1933
