(Read the man page!) Also, a SIGUSR1 could be sent to dd every second or so and then the values of the last output could be used. Of course some sectors will be total rubbish then, but maybe some data can be restored, iff the fs isn't corrupted too much after that. Making backups is the best option, though. :) Greetings, Mike Dornberger - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
