When the dvd is loaded, the laser tracks to the inner ring - focuses, then spins up.....
I think yours is not focusing......
If you are abit nimble you may want to try and open her up and have a tweak with the dvd power supply potentiometer........I have never done that on a PC Dvd so could not really advise you any further on how....sorry....
Maybe worth just giving it a clean first and see if that brings it back.......
this a new drive that has been in the machine for a few months but not used for anything dvd-related until now.
here is the update on this situation. as a last ditch effort i switched the data cables on the mother board thus moving the nd-1100a to the secondary/master slot and the lite-on cdwr to the secondary/slave slot, even though they are both jumpered to "cable select" (this is an asus a7v-266 with four ide slots). viola, it worked the drive began to identify all dvd media...until i rebooted. then it reverted to the same old problem of not seeing any dvd media. this has since corrected itself again but....
everytime i run DVD Shrink it gives an error about 3/4 of the way through and quits. dvd decryptor won't comeplete a rip either. i forget the shrink error but it is something about "program error: something something".
what gives? can anybody figure out this riddle? are these two situations related?
