For a number of months now, I've been experiencing strange file system
errors when trying to defragment my hard disk (a Samsung SP254N, Spinpoint
P120 series, 250GB). To be more precise, the defragmentation software
invariably will encounter problems in the file system.

Now I suspect Webroot Spysweeper may be involved, since I have been using
that for some months, and it appears the problems started at around the same
time...

So I was wondering, to all other Spysweeper users out there, have you had
any similar experiences with this?
