Sometimes my Nexto OTG ND 2300 starts doing a capacity check, and it never stops. It does not respond to "L" cancel command. Hooking it up to the computer does not cancel or interrupt it. Inserting a card does not stop it. It sits in this mode until the battery is dead, and that can take hours. Then once I recharge the batteries, it seems to work again.
How can I STOP this from happening. It's very annoying.
