It could be more optimum. :-) My thought is that I could maybe use a better bs= to make the whole thing run faster. I understand that for every unit, a subprocess dd | grep is started and an if [] test is run. Maybe doing this with 1 MB per unit would be better? Note that I need to grep through 1 TB in 10 kB steps... > Just to make sure, you've stopped daemons and all the stuff > that could potentially write to the drive and nuke your > blocks right ? Of course. The /dev/ad6 disk is a separate data disk which is not in use at the moment (unmounted). Still it is possible that the block has already been overwritten, but when the search has finished, it's almost certain in what state the data is. I would rewrite the file, but my eidetic memory is not working well anymore, so I can only remember parts of it... :-( -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
