If the disc does not appear:
  • Test with another USB cable
  • Try unplugging the drive, turning it off, reconnect, then turn it on
  • Install the latest drivers from the motherboard, including the USB drivers.
  • Check the website of the hard drive manufacturer if there are no special drivers.
  • Check also if it does not have a section with answers to frequently asked questions (FAQ)
  • Check (if possible) the position of the rider in the rack (Sata1/Sata2 for a SATA disk) or the master position (IDE Disk)
  • Plug the box's hard drive directly on the motherboard to check if the failure is due to camera or hard drive
