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=3D/dev/random of=3D/dev/da0.eli bs=3D1m Once that done try to read the data back and look at the logs to see if any corruptions are reported. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com FreeBSD committer http://www.FreeBSD.org Am I Evil?
