I have been trying for a day and a half now to replicate the issue in a Smart Playlist, however, it has not happened. It has happened in folder views again. The only Smart Playlist I use is recently added, so there have not been as many browsing attempts to that as the folder views.

Gusnor, you make an interesting point. I will look into the power settings on the drive. It is actually a RAID device attached vie E-SATA. The thing is, this sometimes happens after one file is finished playing and I browse for a new one.. so I know the drive was being active.

Thanks.
