Hi, can anyone help. I have installed a new 1 TB hard drive identical to the original one, it is a Seagate 1TB video hard drive. The TV section works fine, but when I try to record it says unable to record not enough space, and when I try the device manager and ask it to format it says format unsuccessful. I have also returned it to shipping condition but still no joy. When the hard drive connectors are connected the set is rather erratic, but if I disconnect the two connections to the hard drive the TV section works fine.
