- Writing Quality

Unofficial firmware releases change the maximum supported writing speed for certain media that can only be written at 4X or even lower. It is interesting to see the writing quality with such discs, using hacked firmware. For reference reasons, we demonstrate the following KProbe scans, along with the PlexTools scans.

Note that all the following media was supported only at 4X by official v2.15, while with the un-official firmware (Herrie's 1.07v2beta6) it allowed up to either 6X or 8X.

• 3A DVD-R 4X @ 8X

• BenQ DVD-R 4X @ 8X

• CMC DVD-R 4X @ 8X

• MAM DVD-R 4X @ 6X

Reading error!

• Memorex DVD-R 8X @ 8X

• MMORE DVD-R 4X @ 8X

Reading Error!

• NTech DVD-R 4X @ 8X

• Promedia DVD-R 4X @ 8X

• Traxdata DVD-R 4X @ 4X

• Traxdata DVD-R 8X @ 8X

It seems that the writing quality has totally changed for this drive. With the hacked firmware we were able to write at higher speeds, but writing quality is reduced. Some discs produced read errors, and MMORE discs produced PIF errors. PIF errors were not reported with all other discs, but PI levels were higher than those we show when the official firmware was used.
