I have a weird problem I have not been able to figure out.  I have an external eSata HDD and it is usually off.  But when I do turn it on when the Vista is already loaded it does not detect the HDD unless I go to Device manager and scan for changes.  In Xp it acts as a plug n play and whenever I turn it on Xp automagically discovers it for immediate use.

Any Ideas..

BTW If I connect the external drive via USB vista works fine in autodetection of the drive however I bought eSata for the speed of transfers so dont want to USB if I can help it.  The case is a Vantex Nextar
