I recently ran out of blank DVD+R media and purchased a 50pcs spindle from Best Buy of Memorex DVD+R 16x discs. I tried over half of them with ImgBurn at 4x, 2.4x, then 12x and none of them worked. Kept getting the I/O errors at various places throughout the burn. Figuring that I had a bad batch, I went back to Best Buy and bought a 50pcs Verbatim spindle of 16x DVD+Rs. I've tried about ten of those and am getting the same problem. They're working a little bit better in that some of them write the whole image, but then fail during the verification process.
So my question is do you think I've had crappy luck with two bad batches of media? Or did my drive suddenly go on the fritz? I'm using a SONY DRU810A crossflashed to a BenQ DW1640 with BSRB firmware. It's been working fine before I bought this new media. The media I was using before I was having problems was Memorex 16x Printable DVD+Rs and they were working just fine, which is why I'm led to believe that this new media is crappy.
