The writing quality of AOpen EHW-4048U was average. The drive doesn't seem to like Mitsubishi Chemicals media when JustSpeed is enabled and the number of C1 errors is high with the Octron (Ritek based) 24X media either with JustSpeed enabled/disabled.
- C1/C2 Error rate from Mitsubishi Chemicals 80min 48X @ 40X (JustSpeed Off)
