I recently bought a SONY DVD Burner, and i hooked it up to my labtop usb... I burned a DVD yeterday with no problems, but when I turned my computer on today the drive wasn't detected by windows... I turned the computer off and on and suddenly the drive works! I then turned it off and on again to make sure it was working, and once more it isn't detected... And it hasnt been detected for several attempts now..MY burner is only detected about 10 percent of the time..I'm so fustrated..I don't know what's wrong, because sometimes windows will detect the drive and sometimes it won't. There are no loose connections! Please help me with my problem.
