This tip from Brian Livingston's Newsletter:
A friend of mine was downloading Service Pack 4 for Windows 2000 on his laptop when his system locked up and gave him the Blue Screen of Death. Microsoft acknowledged that this does happen sometimes, and the only solution was to reformat his hard drive and reinstall Win2K.
He came to me because he had a substantial amount of data on his system that he couldn't afford to lose. In essence, what I did was boot to a floppy and then re-size the existing NTFS partition with Partition Magic. Next I created a new FAT partition and installed a new copy of Win2K on this partition.
Once the Win2K installation was complete, I had this installation of Win2K recognize the NTFS partition and, presto, all of his data was accessible. I've left out a few steps, but to me this seems like it's pretty easy to get to this data.
