I purchased one of these drives 8 weeks ago and have successfully burnt over 100 shintaro +R DL discs aswell as around 20 melody BD25's..
About a week ago I noticed that every now and then when a new blank DVD was inserted it would take much longer to recognize..
It's gotten progressively worse to the point where inserting almost any type of disc results in failure to recognize it. ('Incompatible medium' in imgburn..) There is also a small noise that comes from inside the drive when it's trying to read the disc..
The only way I can remedy this is to first insert a CD.. once the CD is recognized (sometimes not straight away) it will pick up any DVD/BD fine.. after 4 or 5 discs it goes back to not recognizing them anymore and I have to put a CD in again... o_0
I have another pioneer burner installed aswell which has no problems reading discs at all..
Any ideas? seems to me the drive is dying - it's only had 8 weeks of use!
