Asus drw-24b5st

Is the ASUS DRW-24B5ST a LiteOn clone? Can it be crossflashed to a LiteOn drive?

ASUS DRW-24B5ST = LiteOn x24 C
ST = 124, 324, 524
LT = 224, 424, 624

I am assuming that it is not possible to crossflash the DRW-24B5ST to a LiteOn. Is it possible to perform reliable quality scan tests with the ASUS firmware?
