I bought a Samsung R720 in July this year running Vista, everything worked as it should and i was very happy. I did however get a notification with it to say i was entitled to an upgrade to Windows 7 upon it's release. Brilliant i thought, better operating system and for just Ã‚Â£17. It arrived on Saturday 19th December and i installed it, everything seemed to be ok (after downloading some updates from Samsungs website), that was until today when i tried to use the dvd drive. When i try to open some photos on discs the drive has an intermittent fault, it either crashes the system altogether, does not recognise the discs or the drive disappears from the device manager completely!! Frustrating is not the word - don't know whether i need to uninstall the driver and re-install it (although i can't find a driver on Samsungs website) Wish i had not bothered upgrading to the so called 'better' product!!
