windows 7 - How to fix a Micro SD card inside a USB 2.0 adapter that is not working?

I have a Micro SD card inside a USB 2.0 adapter that is not working. 
I have tried a few different methods to fix my flash drive with no results.
The micro SD card is 32 GB inserted into a USB 2.0 adapter.

• When I plug the drive into a port, Windows 7 makes a sound, and I am prompted to format the drive. I failed after a number attempts to format the drive. I tried all the ports on three different computers (same results).


• Next, I uninstalled the USB driver and reinstalled the flash drive FAILED


• I opened CMD, entered diskpart > select disk 1 > clean
  and I followed more steps that I found online but still FAILED


• I changed the LETTER of the drive, then continued the step above FAILED


• I tried to insert the drive into my Xbox 360 to try to format it FAILED


• I tried four different recovery programs FAILED


• I tried to format each sector (it took 3 hours) FAILED


• I removed the card from the adapter and placed it into an SD card, then inserted it into my laptop FAILED


• I tired using a micro USB adapter to connect to my cell phone to erase ALL on the drive FAILED


• I tried to use ERASER software to delete all on the drive FAILED

The drive was working fine two days ago. It was used to store video games and add-ons on my Xbox 360 console. Two days ago, I went to play a game on the drive, but it wasn't there. In fact, the console read the drive was almost full; however, the contents was empty.

I would like to delete, erase or reset the drive so I can use it again. 
I don't need to recover its contents;
I can always re-download the games and stuff.

What can I do?
