Oh ... ok, you meant lightening struck and a power outage occured in your home the
previous Sunday. Your computer reads and writes CDs just fine, but not DVDs?
You tested the DVD disks in a friend's PC and the same results?
Ok, I understand now. If the power blackout (or brownout) did not destroy your equipment
because you had a surge protector, it may be a temporary glitch in the operating system.
Try uninstalling the drive in the Device Manager and reboot. If the DVDs did not work in
your friend's PC, assuming that it is healthy one, then it must be the disk's fault, or format.
Other than that, I can offer no further advice but warranty issues.
Yeah, I too, learned English as a second language. After all these years I am still learning it
as I go along. I thought you were just being poetic. I fall down when I read poetry.
Proton ehh? ... Is that the Russian Proton rocket? Well, nevermind ... just a side thought.
