If Windows does not recognize your external hard drive, please check the following:
In the Control Panel:
* Double-click Administrative Tools,
* Click on Computer Management
* Click on Disk Management.
* If the external hard disk appears, it is necessary to partition and then format it so that it appears in the workstation.
+ See here: New hard drive: what to do?
* If the disc does not appear:
+ Test with another USB cable
+ Try to disconnect the drive, turning it off, reconnect, and 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
