Memory Card Not Working

[ernestyeoyx]

Am using a Samsung class 10 64GB SDXC for my Xperia z3 D6653.

Formatted to exFAT.

I can transfer media and all that , but the limit is 4GB . After I have used up 4GB of memory in the SD card , every file above this limit will be deleted .

But , the 4gb limit only happens to FAT32 isn't it ?

I need help fixing this,lurked around but haven't found a solution , Thanks !

Edit ; on 4.4.4 KK , 23.0.1.A.5.77 . 
Edit 2 : Tried using USB Transfer cable MTP mode to sync Media Go , manual transfer , wifi transfer and used SD Card Adapter / Reader . Problem Persists

Yes,you should have about 59.6 available. @Rickard or @Johan will assist you here.

I tested this here and for me it works without issues, both using MTP and MSC.

To me this sounds like a bad or fake SD card. Even with FAT32 it would not explain the issue you're seeing. With FAT32 you can't write single files larger than 4GB but you can still write for example 10 files that are 2GB in size to the card.

Did you run a test of the card using H2testw as suggested by Thommo? Make sure you test all available space with write+verify in the application.
