Writer: LG GH40F, GH22LS40 OEM for Acer with Labelflash support
The worst drive I ever had, thought that it’s faulty, but then I found some complaints on the web proving that it’s simply a terrible burner.
All discs burned and scanned in Dec 2019, same parameters:
Burn Speed: 8x
Software: Nero CD-DVD Speed 126.96.36.199
Media: Verbatim DVD-R 16x
MID: (MCC 03RG20) old good batch, very small scratches at the outer area
Media: Imation DVD+R 16x
MID: (MBIPG101 R05) 2013
disc 3 after cross-flash to GH22NS40, NL02 (disc 2 burned on original GH40F sw gave very similar result to disc 1).
BenQ can’t read the disc.
Seems that transition from CAV to CLV around 0.4 GB mark is a FW bug.
Then I thought that I will keep the drive for Labelflash, so I took some scrap discs to test DiscT@2 feature - the burner managed to overwrite the data twice, I won’t test another time!!
And scans before and after “tattooing”:
Just to check if I don’t make any mistake myself I tried a third disc but on PLDS DH16A6S drive, and the result was as expected:
Seems like the first drive I shall convert into a laser engraver
