If you can't find the "nvata" key in the registry, you can navigate to HKEY _ local _ machine \ system \ current control set \ service \ nvatabus and click "nvatabus" to create and set the "DisableRemovable" key.
After restarting the computer, the system will not recognize the SATA hard disk as a removable device, and the "safely delete hardware" icon will disappear, which will not affect the normal use of other removable devices. After inserting devices such as USB flash drive or mobile hard disk, the icon "Safely delete hardware" will still appear in the system.
Because it is a serial hard disk and the motherboard is a certain model of nforce, it will identify the hard disk as a removable device.
