SD card disappeared from 3 of 6 cameras

It was functioning and receiving clips the last time I checked, but now its just not there as far as the web UI says. I power cycled one of them but it didn't help. Is there anything else I can try that doesn't require opening up the camera?

This seems to have something to do with the auto reboot function. When I clicked "manual update" under System, Auto Maintain, the SD card came back on each camera. I'm not sure why that would work when power cycling didn't. The next night, one of them hit its weekly auto reboot and the card disappeared again. I have disabled auto-reboot on the affected cameras and am waiting to see if the cards stay online.
