Here a comparison between BSJB and BSKB with the same Disk RicohJPN W21. Burn Speed was 8x. Solidburn: default off. Overspeed default off. WOPC on.
This Disk is now a Coaster :Z , going back to BSJB i was not able to format or rewrite with DW1640 (BSJB) or DW800A.
Anybody similar experience with RW-Media?
