Weird behaviour with a SD Card

When using a SD card on a CDJ3000 and trying to save a hotcue it gives a write protected error.

The thing is it works fine until it doesnt, when it gives error on a single song it will give a error forever.

I'm using a Micro sd card adapter, i just tried 2 adapters and the issue is the same.

Its not the lock, because if its locked i cant even load the card into cdj3000

In cdj2000 this is not happening. 

I tried on 3 different CDJ3000 . firmware is 3.11
