dfrgntfs.exe fails because it can't talk to my hard drive?

[draak13]

Like many others, I am using vista, and dfrgntfs.exe gobbles up an entire core and doesn't let go. However, unlike many others, this is a new problem to me, and it only occurred when I installed my new hard drive, a 1.5TB Seagate LP.

I know, Seagate has horrible hard drives and they make bricks faster than a mason blah blah blah...but listen first. Aside from this bizarre issue, the drive is fine.

This hard drive is completely filled with media files; all files larger than 64mb. If I have the hard drive actively open and watching files, the program pegs at full core useage and doesn't let go...and that's about that; I suspect that no files are actually being defragmented. After a while, the hard drive will actually spin down...and then I'm really in trouble. If I try to access this hard drive while it's spun down, and while dfrgntfs.exe is trying (unsuccessfully) to defrag it, explorer crashes. I can restart explorer through control panel->run, but it's done...I have to hit the restart button.

Is there any way that I can make dfrgntfs.exe and my new hard drive play nice together, or do I have to try to completely rid my computer of its existence?

If I instead try to use the command line program defrag, this hard all other hard drives complete just fine, but this hard drive again just spins down and doesn't care. However, command line defrag doesn't crash explorer, either...and I can kill that one.

I'm running vista64 sp2.
