Do you know what you are talking about ?

Why do you need this for ?

Do you intend to sell/provide this info to some WD tool maker so they can implement reading/writing of ROM code by TTL ?

People who have this info will not tell you how to do it as they would be able to implement it themselfs and make $$$ out of it !

Maybe he should ask AceLab or research it himself.....

:shock:

I do know that you really want an update so that you can fix your drives with broken ROM by TTL but why should someone help the SeDiv author for free when SeDiv costs $750 a copy ?

Nice

Should explain why the same Toshiba CPs that PC3K reads with incorrect size are read with incorrect size by SeDiv as well....
