Probably like most people, I bought this unit to back up a whole heap of work data, video material and other stuff to clear out my PC. Having half filled what was supposed to be the available space, it crashed......several times.....and despite disconnecting, waiting the prescribed ten minutes and reconnecting which initially worked, it appears to have now died completely....so nine months worth of work has completely disappeared. It simply refuses to be recognised by my PC....and none of the peculiar sounding programmes that appear to be associated with it (Twonky?) have any effect whatsoever.
The online support is non-existent....so unless you want to buy a piece of useless modern art, do not buy this thing.
I have now ordered a multimedia hard-drive from a different maker, and can but hope it will be better. I bitterly regret spending nine months trusting this bit of crap, and now have to try and replicate some, if not all, of the data I trusted it with.
