I have a trouble with NEC ND-7551
on the laptop Asus L5Gm.
NEC ND-7551 perfectly reads burned CDs and DVDs
but very poorly read industrial manufactured DVDs.
I’v replaced it in the shop with the other one.
But replaced NEC ND-7551 have the same problem.
I’v connected it to the desktop with the help of the
On the desktop everything works ok.
All media was read perfectly.
My original CDRW being installed into the laptop
was configured as Primary slave.
I dumped firmware of the NEC ND7551 with the binflush.
Then I flashed it 1.02 -> 1-P2 on the desktop
by the reverse firmware from the NEC
Flashing was successful.
On the desktop DVD works fine in the reverse state too.
But when I plugged it to the laptop, it still
has the same trouble
So the source of the trouble is my god damn Asus laptop!
Now I need to roll back to the original 1.02
firmware to return the DVD to the shop
to get my money back.
What can I do to turn to the original firmware?
My NEC is now in slave 1.P2 state.
May I flash it now with the dumped firmware (1.02)?
