Information request

I think I had this question answered b4 but I can't find it in any
archives...afer a recent crash and reinstall of WinXPPro, I cannot access
some folders on my old hdds. The last time I had this issue, somone gave me a
command line workaround that released access to the current user... can I get
that information again?
If U always do what you always did...
you';; always get what you always got!
