[quote=shortstack;2005656]I am referring to my Dell Laptop Inspiron E 1505 with DVD±RW DW-Q58A. I am asking about firmware because of a recent problem with my DVD drive. I have been trying to diagnose the problem myself and I keep running into more terminology I don’t know.[/quote] Hi shortstack, I just read your other thread. This is not a firmware problem, this is a DMA problem, your drive has most likely slipped into PIO Mode and you have to reset it. Do a little search here on the forum and you will find many threads on this subject. I would not recommend flashing the firmware on your drive, if you are not familar with this process, a bad flash could ruin your drive and this might not even be the cause of your problems.
