Dear friends,
I am writing from Italy, please forgive my bad english.
I have a QSI (Quanta Storage Inc) DVDRW SDW-041 broken in my Compaq laptop. This device seems almost impossible to find and official centres ask for lots of money to replace it.
Does anyone know what new devices are compatible or how to find information about QSI devices compatibility?
Thanks.
