Your ideas didn't get me anywhere, but thank you for taking the time to
write them down just the same! You are right, this might very well have been
an issue with a weird embedded device.
I could read the card under Windows without a flaw. Because FreeBSD refuses
to access the card, I copied all the files off it under Windows and
completely reset the card. This means, I created a new partition table
(simple type) and formatted the SD Card. Windows and the camera can read the
card without any issues. FreeBSD still can't.
But talking about sanity checking...
Is there some way to get an error message that says a little more about the
cause of the problem than a general failure?
