These are Ritek rebranded discs, poor quality when recording with my LG wh14ns40 drive, even at 2x with IMGburn will burned the disc successfully, the problem In fact there are hundreds of bad sectors on level 2 on this drive. So far I haven't had any problems with Verbatim hard drives, go back to Verbatim. I pay more money and reassure you with your dates. Layer 1 is fine, no errors, so buy if you plan to burn less than 25GB. Update they were happy to refund me, I don't know if I got a bad batch or not but I ordered a more expensive Verbatim brand and got in touch as soon as they arrived.
