Thanks for the replies, ive managed to install it properly now. It was the jumper seetings at the back
....however, there is now an intermittent problem with it not being recognised as a DVD R drive. When I open the door, on the 'my computer' screen it shows as a DVD R drive, but as soon as it closes it reverts back saying its a CDr drive with a DVDr disk in it...obviously this causes problems when trying to burn large amounts onto the disk...I am definately putting in a DVD r disk in BTW!!
Is this a known problem with the initial firmware(DR10)??
Thanks again for any replies
