Since update to Mojave SD card disappears after sleep Since an update to Mojave, the SD card which I use permanently in my MBP 
always gets unmounted after longer sleep and importantly, it does only remount after restart. 

I know this question has been posted several times. However, the only solution I found which is supposed to solve this problem automatically (the tool "Mountain") is 

A) not doing the job

B) crashes the mac sometimes I guess after hitting the "reactivate USB drives command

Anyone has a solution for that?

here some system.log details during sleep:

So its a problem with disk sleep. Actually the one have to disable it manually. In Terminal type: sudo pmset -g and than sudo pmset -a disksleep 1410065408.
