microSD Card disappearing on CCR1009

Hi All,

I would like to ask for help. I have new Mikrotik CCR1009-7G-1C-1S+PC. I would like to use microSD card in it, but I have issue. I have inserted Sandisk MicroSD Ultra 16GB, formatted it to ext3, everything was fine router is able to see it and use. But when router is rebooted SD card will disappear and router is not able to see it, only solution is to disconnect router from power supply and connect it back, after reboot without power disconnect SD card will never came back. Do you have idea what could be issue and how to solve it?

I’m running 6.37.4 (Bugfix only).

Thanks,

David
