If you still can’t remove the read-only of the drive, reformat it using diskpart or 3rd-party software,
or use a non-windows machine for reformating of drive to ensure the success of resetting drive/partition flags
So I faced the exact same problem today. Luckily I already had a software called as “Mini tool partition wizard” which I installed before for other purposes but it really helped me this time. Just google the name and you’ll find this small tool.
It looks like your “Disk 3” says “Unformatted”, you need to right click and click “Format”. Then choose a filetype. You can either choose NTFS, FAT21 or exFAT (all the three are good for Windows). Then “Apply” the changes. I think it will start working.
Note that Formatting will delete everything from your drive.
I noticed that in your screenshot it says “Read Only”. There could be many reasons that happens. Maybe the hard drive is corrupt or there might be some kind of physical button that makes the drive read only (although that rarely happens in new drives). In most of the cases, I think formatting the disk should remove the “Read Only” problem.
