Last time I bought +R DL verbatims they turned out to be MKM 003. I didn’t even noticed this until nero disc verify failed. Nero DiscSpeed showed PIF spike at cca 500MB before layer break and huge one at layer break. Disc was unreadable after layer break.
I burned it and scanned with Lite-on DH-20A1S with 9L08 firmware from LH-20A1S. I also updated it’s firmware to 9L09, and also flashed it back to DH-20A1S UX14 firmware. But PIF spikes were present every time. Best disc score was about 40. MKM 001 had 95…
I also tried with Asus DRW-1814BLT 1.13 firmware and also with 1.14. Results were somewhat better, but quality was also nothing spectacular. Best results were with old Lite-on SOHW-1653s. It also had two spikes as the rest of them, but they were smaller so scan score was 70. Write speed was 2.4x, max I could choose. Other discs were burned at 4x.
So, is there some burner that can write to these MKM 003 reliably? Preferably SATA drive.
