USB 750GB HDD disk suddenly became non removable.

[mxnerd]

Tried on 2 Windows 10 machines.

When right click the drive, there is no Eject menu option.

How can I fix it?

OK, I think I got it.

The other day Windows complained the recycle bin on the disk was corrupted so I recreated the Recycle Bin on the disk using command line.

Didn't realize that it makes the drive non removable. Duh.
