I have a Matshita dvd ram UJ-851S ATA device on my compaq presario V6000.
The problem i am having is that it does not say in device manager under dvd/cd rom drives, that i have the disc drive.
I have tried to remove upper and lower filters under regedit. this still does not work.
It occasionally comes up with installing device driver for the cd drive and it will work....then it stops again.
Anyone know what the problem could be???
It seems like this is a common problem for this model and a few other compaq/hp models. I couldn't find any solutions around the net, but if it is available for hp's support site, try updating the firmware on the drive and see if that solves the problem.
