The issue of the upper lower filters repeats as we do some things. I missed where you deleted these this time.
hi guys i need your help with my laptop on xp sp2
after looking throught this forum i can see that this is a commomn problem but all the solutions given havent worked on my laptop,
suddenly i "lost" my cd/dvd rw drive on my hp laptop, i did the usual and deleted the upper and lower filters in the regedit, and it worked, but now it gone again, ive tried re-installing the factory drives from hp and thats done nothing, sometimes it appears as a dvd-ram drive in my computer but it wont read cds, the drive itself is fully functioning and opens and closes and spins and the light flashes but thats it!
ive got a good knowledge of computers and thought it would be an easy fix but this is proving difficult,
if you could offer any help at all that would be greatly appreciated
on a final note, i was told to try boot from cd, at the time i couldnt find my windows disc, so downloaded a simple memorey test and burned it to a disc and booted the laptop from that disc, this was succesful which i presume means the drive is fine,
