Ah yes, I have the drive mostly for backup purposes, but with one partition where skydrive syncs to, with the new office also syncing. Just curious though, should the same delay occur when I disconnect the drive? I did, and it did occur. I'll look into the power saving. I'm guessing it should help if I move the O: partition to the caviar black drive? And just for my understanding of the traces: you mention activity before I stopped the trace, this is during the hanging or after?
