It's pretty straightforward.. http://www.the-gadgeteer.com/review/vosonic_vp3320_xs_drive I have one vosonic and a cheapie 'LOOK' USB 2.0 OTG Digital Partner from china which cost me about $35 USD then I popped in the hard drive myself. I spoke of both of these quite some time back.. the advantage of the latter being it had a USB interface rather than specific card slots so all one needed was a simple USB card reader appropriate to the card then hit 'copy' and the lights flash then it beeps to tell you the job's done :) I don't think this style is available any more (might be wrong!) but it was nice - plug in the flash drive to back that up, plug in the miniSD reader and back up the phone, the sony memory stick reader & copy everything, switch in the CF USB adapter and there we have it - everything I owned backed up :) No display though which is a good thing - the battery lasts a LOT longer without having to power a display (most of which are really useless for seeing anything unless they're bigger than 7") and the thing was powered with AA's or rechargeables - a lot less of a hastle than carrying specific chargers or having to rely on mains power when you are in remote locations.. For the laptop users there's also the multicard adapter - I have one similar to this one: http://www.synchrotech.com/products/media-adapters_02.html which I leave in my laptop all the time ( a teeny lifebook with a touchscreen) k
