Data Execution Problems(DEP) when opening HD

[gamer1drew]

Hi, I got a new HD a couple weeks ago. 300 gb sata 16 mbs cache. Worked great, loaded it up with stuff. Now I am getting DEP errors when i view the root of this drive. I am not booting from it and none of my other drives are having this problem. I can access and use files on it, its jsut when I open the root of the drive. Windows Explorer crashes and I get DEP errors. Virus scanned it and error checked it(did not scan for bad sectors). Any ideas? Thanks.


EDIT:
Looks like I got it to stop. A movie I encoded was causing it. Anyone know why this would happen?
