Default [Q] External SD Card

Since I have my Note 3 retted have a weird problem where I have cause not yet obsolete.
If I remove or something new place in my ex sd card and restart it, then that is negated and then state that I did not delete it again, or is that beyond that I have is gone. Posted
Ie mn card is exactly as it was before.
Somewhere is thus always a backup put back but do not know which program is responsible for it.
've Backup program, s removes and then done the same, but that does not matter, then there happens the same. So I think that the unit itself does, but can not find anything in the settings.
Anyone here have an idea?
