I have an Acer Aspire 1356 laptop with a Pioneer DVD-RW DVR-K12RA optical drive.
The problem is, that it can’t start/run a BUNRT DVD-R or DVD+RW (haven’t tried DVD+R nor DVD-RW), I have tried a blank DVD-R and it recognizes it as such (nero opens, etc…).
The fact is, that the drive tries to start the DVD several times, before it stops after few seconds (some noise is noticed when it tries to start it up), then, it is like there was no DVD in the unit, nothing was recognized.
It can read commercial DVDs, but not burnt DVDs.
It can also read CD’s, CD-Rs.
I have tried uninstalling all burning applications, but it doesn’t work, even after a fresh windows re-install, so it can’t be a software problem.
I was thinking that it may be a firmware problem?
I have used a DVD lens cleaner several times and nothing.
As I’m getting desperate, i’m thinking of taking apart the unit and inspect it (warranty is expired), but it’s not as easy as that, as it is a laptop, so I would like to hear some advice from you before doing so
Thanks in advance.
