★ You take your mobile hard drive to someone else's computer and see if it's going to happen.
If this problem does not occur. It's your computer system problem. If the antivirus doesn't solve anything,
You can only reload.

And if you move the hard drive, can you go in now?

★ If you can get in. Just backup the data.
Right-click My Computer
Select Management-> Disk Management-> Select D disk Right click-> Delete Logical drive-> then select free Space-> Right-click New->-> set size-> tick Quick format->

★ If you can't go in
It means that you have a problem with moving the hard drive itself. If it's still under warranty. Take it back and put them in charge.
If that's the case. It's going to have to be formatted anyway. Maintenance because the disk has been changed
