Recently I decided to replace my aging benq DW1620 with Asus DRW-24B1LT which, as I understand, is actually LiteOn iHAS424 inside. In addition I have an additional drive capable of error checking: Samsung's TS-L632H.
I checked a couple of DVDs recently burned by benq in all 3 drives, and got very different results, see an example attached (those are results of a test of one dvd in all 3 drives).
Since results are so different, which of them tells the truth? According to LiteOn, the burn is extremely bad (though the drive doesn't have any problem with reading the disk), according to Samsung it is just not very good, and according th BENQ it is good.
Who is right? How it is possible to interpret so different results?
