My board sees the 4Gb microSD card fine, can format no issues and move stores for dude, usermanager and proxy across. After a reboot it can no longer see the card and the stores default back to system, showing the old locations as invalid.

Only way to get the card back is to reseat it.

Anyone else seen this?

Thanks in advance...

What's the make/model of the card you are using?

Sandisk 4Gb... I believe its on the compatibility list? I've seen it on a couple of boards now with the same make card...

I have the same issue. I reboot and doesn't appear. I will remove and put again the microSD and try again. I can't do this now because is a remote router.
The micro SD is markvision 8gb

I was having these problems with a class 6 Kingston card. Was hoping the Sandisk cards would be better since they show up more often on the compatibility list. I'm not longer having the problem with RouterOS 4.7 so I'm wondering if it may have been related to routing related crashes.
