I have an external eSATA drive (WD mybook studio 2TB) that I"m trying to use for time machine backup. When I start leopard, the drive does not show up unless I unplug the esata cable and replug it in, then it works fine. 1) Why isn't it recognizing the drive on boot? 2) Is there a way to force a "rescan" without physically unplugging? 3) Other tips? thanks!
