I did this for a friend - it took me a while and some googling but I did manage to pull everything off the dead laptop's drive. I logged in to my machine as admin, plugged in the dead laptop's hard drive using a cheap USB enclosure like
this, then transferred the permissions to me. Once I did that, I re-copied everything to a WD 160-gig portable hard drive and my friend used that to repopulate her new laptop. If I remember correctly, it took right-clicking on the files and selecting "properties", then under the "security" tab, resetting to me. At first I had to do this file by file, but then with some googling I found a way to either do it by directory or by selecting multiple files - I cannot remember which unfortunately.
Google it, there are plenty of sites out there that tell you how to do it. OK, first google search I did brought this up:

Check out the "chandlerjea" response, I believe that is exactly what I did.
