[Q] SD Card very weird behavior - unable to format or delete topic

I have an extremely weird SD Card behavior with my Note 2:

• After deleting files and rebooting, the files reappear.

• I can't format the SD Card using the Android OS - it goes black screen and requires me to pull out the battery in order to start the device.

• I removed the SD Card and attached it to my laptop's SD Card slot and tried formatting using Windows 7- the format process completed after ~30-40 minutes, yet the SD Card appeared UNCHANGED! :mad::mad::mad:

• I used multiple SD Card formatting tools, still no dice - they either complain about write protection, that they can't start, they start and stop halfway with an error, you name it.

It's like the SD Card has built in protection that keeps the files in it in stasis form, never ever witnessed such a behavior in any storage device. What gives?

Any help, preferably from people who may have encountered a similar behavior, will be greatly appreciated!
