That Disk Checking Blue screen! ARGH

Once in a while when I boot XP, a blue screen telling me that I should check my C: for errors comes up. It does this CHKDSK thing, but it usually never finds errors.

However, there was this one time when it actually deleted a Windows DLL file, which actually prevented me from logging into my machine!

It took me a couple days to track down exactly which DLL it deleted... what a pain in the butt. Is there a way to disable this autochecking ?
