I'm trying to read the files from a digital camera,
and get this error:

I've had this problem before:

http://lists.freebsd.org/pipermail/freebsd-sparc64/2011-September/008050.html

and simply loading GEOM MBR module helped.

However, this doesn't seem to help now.

Please advise

Many thanks

Anton
