Hi! I set my backup server the other day, it works like this. Using a Batch File it copies all the folders to be backuped from my file server onto 2 seperate 160 Gig HDD's in removable Racks. BUT! I need a way to switch the hdd's on and off. The problem I am having is when I turn the key on the rack itself the hdd doesnt really switch off. So I need to make this hot-swappable or something like this. I dont know if this is possible, any advice...?
