[QUOTE=memory;2658136]thanks but that was not the problem.
Sony DRU-810A ([B]some[/B]) *, DRX-810UL (ext/some) , DRX-810UL/T (mac/ext/some) *
 Be EXTREMELY careful before crossflashing the Sony 810 series drives! Make sure you know if you have a DW1640 or DW165x before attempting to crossflash!
that “([B]some[/B])” was the problem.
what was meant with this “([B]some[/B])”?
before i kill a drive i ask two times. ;)[/QUOTE]
That means that you can’t always tell by the model number on the outer packaging, you have to physically inspect the drive to know for sure.
For external drives, you can’t tell without opening the enclosure up.
BTW, on the next to last line of the list of drives, you need to add “(mediatek/lite-on)”, because that was actually supposed to be a single line that got split in two.
