  • 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 on the website of the manufacturer of the hard drive 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
