I am studing the 1st course, so it is still a long time before I am an industrial engineer, I AM IGNORANT, I SAY IT MYSELF, I CAN LEARN A LOT MORE.
I did not suggest flashing the drive because I think it was not a firmware problem, I'll hope we'll find out soon. I don't have anything against flashing things, I flash my bios, my recorder...
Of course I know it is safer than taking apart hardware, anyway.
But you cannot compare a router with a CD recorder, I don't know many things about routers, but I am sure they have no moving parts (apart form a fan to keep them cooler, maybe), so there is no need to remove dust from their insides, a CDROM drive is very likely to have a mechanical problem, as it has a lense which has to be clean, a lense which moves along rails, a tray...
I am the first one who knows that when somebody says "My computer is broken, I need a new one", it is probably a problem with their software.
ALL RIGHT, I FORGOT TO RECOMMEND FLASHING A DAMN NEW FIRMWARE, I AM VERY SORRY FOR THIS.
Please don't discredit me in the forums, so far I think I have not given anyone bad advice (if you can prove it do it, I will admit my failures).
SEARCH FIRST, THEN POST
