As he stated, it forces a GEOM retasting which is something necessary when
dealing with removable media.  However I don't think it will help in this
case as the device is already seen.  More likely the problem is the fs
itself.   I'm having trouble discerning the current problem you are trying
to solve given the scattered nature of the thread, but in general trouble
mounting ext2/3 fs results from one of 3 things.

GEOM doesn't see the partion which is what the "true > /dev/da0" fixes
The fs wasn't dismounted cleanly and needs to be fsck'd
The fs was created in a manner incompatible with FreeBSD ext2/3 support.
