If i put any memory device in, it says i must format the disk before i can use it...but I have alot of information on them and its pointless to delete information that i want to see. If i click on the properties of the disk it says i have 0% unused information. I turned auto play off and even uninstalled ROXIO. With ROXIO deleted, the cd drive now says i must insert a disk but there is already one in there. The other drives still say the same as they did before ROXIO was deleted. This problem started off as the cd drive only messing up sometimes. Then it stopped working completely. Within a few weeks i couldnt use any of the drives. Ive tried many diagnostic tests and no luck.
