I thought I’d just post an FYI on SD cards and RB.
I’ve got some RB450G’s and I’ve added a few 8GB sdhc cards.
They come up invalid - which is expected.
You need to format the cards before you can use them.
[/system stores disk from winbox.]
However, formatting them takes a LONG time. (In my case, like 6 minutes.)
Other than looking at system/resources and noting that CPU is pegged at 100% there’s nothing to tell you anything is going on.
But eventually they completed and all was well.
Thus, if during formatting, things look hung, check CPU resources and be patient if they show ~100% use.
They were class 10 microSD from Kingston and PNY. I don’t have model numbers handy, but take it for what it’s worth.
Also, on the RB450G the cards don’t “detent” insert into the slot - i.e. there’s no click or detent to tell you when it’s fully inserted. It just sticks in and will hang out over the edge of the board like 2-4mm or so.
Perhaps this is covered somewhere, but I wasn’t aware of it and searches didn’t bring anything up.
So, just FYI.
