I have a Sony Vaio FS195XP and did a firmware update for my DVD drive.
However, I installed a D56A firmware on my DW-Q520A burner which caused a big problem.
I thought I had a D56A cause it said it was one in Windows.
Whenever I started my computer, the screen just said: “Operating system not found”
Today at the shop they took out the DVD drive and the computer worked again but they said that the Q520A burner is broken now.
Is that true?
Can’t I just install the correct firmware on it now?
Please help me
