OP’s problem is that after deleting files/images, they reappear on the mSD card.
I got the same problem. Windows cannot complete format, nor any other partition/HDD disk/erase tools.
After deleting/cleaning the partition of my 16GB micro SDHC, I unplug and plug it back in with all the data still there.
I’ve tried to delete the files under DOS, PE and linux with no success, even XP install cannot get rid of the partition on my mSD card.
Does anyone know a solution?
EDIT: I’ve tried with SD adapter(unlocked) and USB microSD adapter. Even in a Smartphone.
