[olug] corrupt master file table (NTFS)

[Dan Linder]

If it's an older system that's been on quite a bit, it's possible the disks
are starting to fail at the substrate level.

You might be able to run SpinRite on it:

They offer a money-back gurantee if it doesn't work for you, but I've had a
couple of drives it resurrected just long enough to pull the data off of
before replacing them.
