asus rt-ac87u: USB drive unmounts + no space left on device

[Martin - SNBuser]

To reduce wear I think you should also use the option 'noatime' when mounting the USB stick.
It disables writing last file access information.

I think it automatically mounts the USB stick when I insert it in the router... Not sure if I can add the noatime to /etc/fstab or if there's an autoconf file or something... Anyway, thanks, I'll write again if new problems appear.
