i have a satellite a75 with the cd/dvd combo in it and just the other day it stopped working. i have no clue why it stopped and when i check the hardware it says it is reconized. when i put a cd in the little cd on the mouse pointer will blink but after about 15 seconds nothing will happen. also the light on the dvd/cd drive will blink when a cd is put in but after it tries to read it the light will just stay constant. the drives are a axv cd/dvd-rom scsi and mat****a dvd-ram uj-820s
