How can I remove 'read-only' for a MicroSD card?

Specs: Windows 10 Pro, Intel Core i3 2.4GHz / 8GB
I was copying files from my MicroSD card in my phone to my Windows 10 PC via a USB cord. I had TeraCopy installed so my PC was making use of it for the file transfer process. I decided not to use TeraCopy so I cancelled the process. But I remembered that for me to copy files without TeraCopy I have to uninstall it, so I did. I received a feedback that I have to restart my PC for the uninstallation to be complete, and I did.
However, my phone was still connected to my PC., and being afraid that something might go wrong if my PC restarts with my phone still connected to it, I disconnected my phone only to find out that my MicroSD (HC class 10) 16GB card has become blank. I tried formatting it with my phone which is Nokia C2-00 but was told that the option is not available for a read only memory card.
Moreover, I have tried formatting it with Windows using Command Prompt, Disk Management and Diskpart all to no avail. I used SDFormatter and was told that the disk is write-protected, although Diskpart shows "Current read only state: No" and "Read-only: No".
Hence, is there still hope for my memory card, and what do I do?

Does the card have a wee slide switch on one edge? If so that is likely a lock switch and its in the Locked - read only - write protected position?

The MicroSD has no lock switch. It shows it's read-only in my Nokia C2-00 though it's not mounted with an adapter. I tried formatting it again and this is what I have below:


C:\WINDOWS\system32>format D: /fs:fat32
Insert new disk for drive D:
and press ENTER when ready...
The type of the file system is RAW.
The new file system is FAT32.
Verifying 15.0 GB
30745558 bad sectors were encountered during the format. These sectors
cannot be guaranteed to have been cleaned.
Invalid media or Track 0 bad - disk unusable.
Format failed.

Good grief. Buy a new card. Obviously that one's bad. They're cheap enough.
