I've gotten an new HDD docking station. Thing is it reacts strangely when I hook it up to my 722k. If I hook it up when the VIP is on it will report that there have been too many devices hooked up. It has built into it a USB hub, esata connection and he line that hooks up to he VIP is a micro USB connector. Well if I reboot the 722k it will see it just fine and be as happy as a pig in mud. Gets real old though having to reboot though. And yes it has it's own power supply and will use either 2.5 or 3.5 HDD's. Reason I got the uni is it is angled so that it is easier for it to sit on same shelf as the 722k. The previous docking station I was using had to sit on a different shelf so that if I wanted to change HDD's I would have to pull it off the shelf and change the HDD's then put it back. This one all I have to do is pull the unit to front of shelf and switch out the HDD's.
