I own an acer aspire 1 windows 7 and was just deleting some files, then I just saw BD-ROM Drive (D:) which is grouped with "devices with removable storage" below the "hard disk drives" I tried to right-click it and eject, but nothing happened, I tried to drag it to the trash bin, but the mouse had this 0 with a / logo in it's lower right portion. I tried to click the icon on the left of my battery icon but couldn't find it. How do I remove it?
