I have burnt two discs thus far with no problems. I examined each disc visually and the die seems to be in good order. Due to the other review I tried two firmwares with my LG GGW-H20L Drive
Burn Details:
GGW-H20L YL04
Nero 8
22,472 MB Data UDF
4x speed selected.
Burn Time: 00:55:20
6,931 KB/s
GGW-H20L YL05
Nero 8
22,699 MB Data UDF
4x speed selected.
Burn Time: 00:55:24
6,992 KB/s
Neither firmware hit 4x speed of 17,980KB/s. There is not a lot in it between the two Firmwares.
Additional Comments:
Drive: LG GGW-H20L YL05
Printer: Epson PhotoStylus 950
Software: Nero 8
I have now used seven of the ten discs from the first batch I have bought. All burned correctly and verified. Print quality of the surface is good too. There is a speed issue though as noted by another reviewer. The drive burns BD-R at 6x. The discs are rated at 4x. Nero 8 offers 2x or 4x burning rate. However a full disc of multiple data files (burnt as UDF data disc) only hit a maximum speed of 1.6x and stayed mostly at 1.5x. This means a burn time of approximately 55-60 minutes for a disc.
I have bought a second set though as they are reliable. No costers.
UPDATE:
AVOID THESE DISCS...
After reading another review about unreadable discs after a year has passed since burning I checked my year old discs. Out of 10 discs 4 are no longer readable, 100 Gig of data gone!!! As it happens I was using these as a backup for some DVD-R (which are even older). I still have the DVD-Rs and they are still readable. So I can reacreate them. Was about to order my third tub, but not now, shall look elsewhere...
