Recently there is a guy dissassemble his DW2000 (with “S” firmware) and take a look on the OPU model, it’s a DS10HLF (Sanyo SF-DS10HL). This OPU has been used in 18A1P/18A1H series of Lite-On drives, now it’s in a drive which believed to use Sharp LD.
My question is, is anyone there with 20A1P or 20A4P “A” could take apart their drive and take a look on the OPU? May be SHARP LD never exist? May be it’s a typo by firmware writer? (SHARP vs SANYO). Can anyone verified the “Mitsubishi” LD is used in previous drives too?
