Hi guys. I have ordered a Zgemma and I was wondering if it was advisable for me to use the hdd out of the sky hd box that is lying around the house. It was always a spare box. If it is advisable, then is there any special cables, or whatever, that I need to buy first. Or should I just get a desk top hard drive(recommendations?). And also what size USB should I use for the epg. Any recommendations on which brand. Thanks in advance.
