Thanks in advance to anyone who can help me figure this out;
When I watch video in Windows Media Player or Media Center, at maybe 15-20 minutes in to the video it freezes for a little while, the hard drive spins up, and then the audio continues normally and the video runs fast for a second or two, then normal playback resumes. It normally does this once per video file. The video files are located on a data partition on my 500GB Spinpoint F1, which has Windows 7 64 bit installed on a different partition.
I'm not sure whether the problem occurs in other programs like VLC or not... I have not been able to find anything about this particular issue on Google.
