I too am having problems with my SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 installed in a Galaxy Note 2. Everything was working fine until the last few weeks. My phone was recently updated to Android 4.3 and now I am noticing this problem. Also I have about 39 GB of pictures and video on the card and also in the last few weeks I am getting corrupted pictures and videos when I take new images.
I tried reformatting the card in Windows and it says Format is complete. But then all of my pictures come back again.

Welp....I can't add, delete, or format anymore, and it appears this issue is shared by several owners of the 64gb card. Sadly I don't see any response from Sandisk, or anyone, on how to resolve it. Are we just screwed and stuck with a crapped out card.....
On a positive note.....I was able to pulled stuff off the card that I wanted and save to my desktop until I get a new card.

I'm having exactly the same problem. All of a sudden, the MicoSD card is in a "frozen" state... I cannot write to it... I cannot delete it... I cannot format it... It "appears" to work... and it appears to accept alterations... but when you remove it and reinsert it... it goes back to the way it was... any deleted files magically reappear and anything new added disappears.
WORTHLESS.. Never buying SanDisk again.

I am so relieved. My 64GB SDXCi in a Note 2 has been acting oddly this last couple of months. Apps not finding data; media players not playing files. I've tried all the things that other correspondents here have tried. I've downloaded and tried several 3rd party formatters (one of which took a while to clean up after it also installed a load of unwanted stuff). I reckon I've spent nearly 3 full days trying to sort it out and in the end I gave up and got another card. Which works fine.
My relief is because I thought I was going mad - or stupid. These posts from others with similar experiences are very reassuring, even if it is a shame that Sandisk has not owned up to the problem.

I am happy to say that when I reported to Sandisk my problem with this card and the umpteen measures I'd taken to try to deal with it - unsuccessfully - they very quickly accepted that the card is faulty and sent me an RMA to return it for replacement. Given that things in this world do go wrong some times, I am impressed with their response. Though I do still think it would be good if what appears to be a known problem with this card were better publicised.

SAME EXACT PROBLEM
No way of formatting.
I believed it started the day I upgraded to 4.3 too (Xperia Z1). This is weird.
ps: I live in Argentina so there is no way of RMA for me
