As has already been pointed out, removing media without unmounting it
first is highly risky - you're risking data loss in spite of ext3
being a journalling filesystem.
The other thing to think about is that with a block based journalling
filesystem, a flash-based device is going to get a higher number of
writes, and therefore will wear out (and therefore fail) quicker. You
might be better off with some other filesystem (eg, vfat) on the SD
card.
Lastly, try reporting the problem somewhere more appropriate, such as
the ext2 maintainers/mailing list and the SD mailing list.
