I recently built a computer with my friend and everything has been fine until about 3 or 4 days ago when the CD/DVD drive stopped working properly. The symptoms are that it will not read any disks regardless of their type i.e. program, video or audio. However, the drive is definately receiving power and the Sata cable is connected because I have no trouble booting from the Windows 7 OS disk, as a test. The drive is also not recognised in 'My Computer' and the properties info gives me the following message, 'Impossible to load peripheral driver for this hardware. Driver could be damaged or missing (Code 39)' (translated from the Italian). For your info the drive model is an LG GH24NS50. Thanks.
