Hi guys, I got an Xbox 360 Arcade pack free with a LCD TV from Dick Smiths and was looking at a HDD for it. 60Gb drives seem to be about $150, but Microsoft lists the 120Gb drive for that price on there site. I noticed that on ebay you can get 'Buy it now' 120gb drives for about $80, with no packaging. Now to my question, I noticed a thread here that said Microsoft are updating the firmware to include a feature to not allow non-Microsoft storage devices. Would the drives on ebay be genuine?, (they look the part, but coming from Hong Kong, who knows?), and would they be likely to work with any future updates?
