I used this Hard Drive USB Dock to upgrade the hard drive in my Thompson 902020 Sky HD box to 1TB using Copy+
This USB Dock transferred the data from my original 300GB Seagate hard drive to a new Western Digital Caviar Green WD10EVDS 1TB 3.5" Internal SATA Hard Drive (also from Play.com) flawlessly.
After inserting the hard drive into the dock and hot-plugging into a free USB port the device was up and running with Windows Vista.
