Thank you both for replying. I went to disc management and the drive is listed exactly the same as D drive with roughly 13 gigs. Drive Manager shows 1 C drive, 2 D drives, 1 G drive. I wanted to use the Vista OS for 2 little programs, one a file lister and one b/u software both that do not work on Win 7. They both worked on XP and Vista. They are both easy programs to use and I am haaving difficulty with the newer ones.
