Extremely satisfied with my purchase. I used in conjunction with the product STOREX MediaZapper HD TV with Freeview box USB input which I am equally satisfied, a very homogeneous group. The Hitachi drive has a large capacity, it does not heat, barely warmed after 1 hour non stop. It comes with a USB Y-cable so require dual power supplies, as most. I preferred for a small fee (16.86) order a USB hub with 4 ports APM food and I only use this power supply connected directly to the disque.J'aurais have sought only power supply but I and the Power + simple cable. The hub will one day supplement. I put aside the USB Y cable supplied with the disc and uses the single cable APM case, it does not serve me but it is good to have in reserve. For that amount, I have a power supply and a USB cable simple, it's perfect. Ultra smooth video and DTT box remote control is acceptable. A very good set in very correct. Very fast delivery as usual the Amazon site, despite the holidays. I recommend these products and notemment this set. The single disc is perfect for backup. I do not use the software provided and prefers a "batch" file personal, everyone's goûts.Donc no comment on the backup software.
