[Q] Is my SD card broken or is an app just write protecting it

I have this Team 64GB MicroSDXC Flash Card Model TUSDX64GUHS03 bought from newegg. My card hasn't been copying files properly. I "successfully" copied videos onto my device according to my PC. Then when I checked the files weren't there and one of the videos I copied was only like 1% of the original file and was named mtptemp.mp4. I can copy files from the card but when I copy onto it'll appear but can't be read. And the free space right now is only 10GB. I also did not set up any type of encryption as far as I know.

I tried reformatting it using several ways. The simplest being unlocking the MIcroSDXC adapter and formatting using the formatter in Windows Explorer and Disk Management in Computer Management. I used the formatting tool from sdcard.org and it will show that the card is write protected. I also tried removing write protect with a guide on youtube by ijusttutor titled "How to remove write protection from your usb or sd card using cmd". Also tried that SD fix app and that says it's unnecessary.

and here's a list of my apps (I removed a lot of other apps which are unlikely to affect the protection of the card)

Now is my card broken or one of my apps is locking it up? Buying one isn't an option right now, a fix preferably please. I'm running 4.3 on AT&T Galaxy Note 3

I see that you have the Xposed Installer. Have you tried the HandleExternalStorage module? It may be a fix, IDK. Try this thread in the forum- http://xdaforums.com/xposed/modules/app-handleexternalstorage-t2693521

Just tried it.. That doesn't work either. Did h2testw, My results from h2testw:

h2testw couldn't scan the whole volume because it has data on it and I can't format it.

I would try copying what you have on the card to your computer, then formatting the card. Once you have done that, place it in the device and then let the device format the card and then place your content back onto the micro sd card.

Won't format on both my device and laptop. That's what I've been trying to do

Tried that already. Says the card is write protected even though I've done all sorts of disabling write protection.

Owned it for more than 5 months and filled it to almost 50GB when it started to fail

I am supposing that it's a 64 GB sd card? Does the device support an sd card of that size?
