It could be that it's died and/or locked in read-only.
How would I unlock it from being read only?
Try to format it with the Panasonic SDFormatter
I tried it but I get "the memory card is write protected. please release the write protect switch" which I did do many times.
If all else fails use a live version of linux with gparted, it never fails (as long as it isnt dead that is)
Where would I go to get it and how to install it.
RIP Linux -
Here
Download the iso and burn it to a cd, and RIP doesnt stand for Rest in Peace it stands for Recovery Is Possible
you load it up and when you get to the commant prompt (terminal) type "root" and then you'll have # appear, you then type "startx" you'll then get a solid blue background, right click and a list will pop up, it resembles the start menu in windows 95, go down to partition and select gparted. Make sure you select the right drive before you delete or format anything because if you mess up and choose the wrong drive you can accidently wipe windows off your pc, its hard to do though so I wouldn't worry much, just choose the 32gb drive from the drop down menu in the top right of the gparted window (it'll be called something like /dev/sdx 32gb). As long as you pay attention to what you see you should be fine
You run this off a cd (you can use usb but its always good to have a copy in storage, thats why i recommend cd) and boot your pc with the cd in, it will load directly into linux, when you want to use windows again shutdown pc and remove disk
Alternatively you can just use a gparted live disk (download
Here) but I prefer RIP linux as it has a few other programs that can help you if ever you pc goes wrong, like Hard drive failure etc, very good for recovering files off faulty drives
Edit
One more thing if you can use a usb adapter for the micro sd, I have problems on my laptop with a micro sd to SD card adapter, linux refuses to see mine, might be different for you though
