I don't know why, but my hard drive is acting slow. I use it primarily for video processing and video storage. I have several dvd images, and the hard drive cant keep up with my burner. It takes about 25 minutes to transfer a dvd image to the hd that works on my computer. Vid editing is extremely slow with this HD.

I have ran avg antivirus, lavasoft adaware, spybot search and destroy and there's nothing that shouldn't be there. I went to the properties of the drive to error-check, defrag, and troubleshoot in the device properties and that didn't help. Does anybody have any ideas as to what the problem could be, or ideas on how to troubleshoot?
