This seems like umass/usb issue (hps@ CCed). Can you also try GELI with
data integrity verification?
# geli onetime -a hmac/sha1 -s 4096 /dev/da0
It will report some problems due to GEOM tasting, but ignore them and run:
# dd if=/dev/random of=/dev/da0.eli bs=1m
Once that done try to read the data back and look at the logs to see if
any corruptions are reported.
