Dave please help me on that.
It reads perfectly DVD's and Audios. But it takes a long time to read a data disk (about 5 minutes) or it doesen't read it at all.
I took about 40 cd's and inserted them one by one. 1/3 of them have been read and 2/3 not.
And it doesen't matter is is a CD-R, CDRW or is it a factory disk. It reads and does not read all of them.
I have tryed to find the driver. But I don't think it is a driver fault as long as all CD drives are using the same XP driver (5.1.2535.0, from 01.07.2001).
I have cleaned the lens with special EMTEC/BASF DVD cleaning disk. No results.
What could it be?
