I bought some months ago a BENQ DVD-RW drive (model dw 1620) and since the beginning I had some problems with it, for instance the drive feezing when burning.
The main issue is that after burning DVDs or CDs and when checking the burned media (CD or DVDs) it has “strange” circles of the burning, the drive doesn’t make a “clean” burning.
I have also experienced strange situations like when extracting information from original media (like dvds) it also creates circles on the dvd.
Is this a sympton of a deffective drive or can this happen due to a wrong installation/configuration?
