that makes me wonder, i know there was a usb drive i saw a while ago, that had a sata port on the back side of it. if that was to be connected to the sata uptop, an xbreboot console would format it and make it work. an easy way to add 5v, i was thinking about taking the original memory card, take out the board, solder a usb plug into it, and have a usb cord coming out the side, so that you could have that plugged into the bottom usb ports on the console to pull the 5v required, i guess run the 5v and ground from the usb at the bottom of the console, then use the data lines from the memory card pins. shouldnt have any problem using an external hard drive tho. since most external enclosures use their own independant power bricks. do external enclosures even use the 5v from the usb??
if i had a spare memory card, dead one even, i would definently make this. i got all the other stuff, just not a memory card i can take apart.
