It's a fantastic encrypted FS. Following the man page, I've tried to use the destroy command but without success. Here is what I did to create the encrypted FS (for this test I didn't use the /dev/random to fill-up the disc). # kldload geom_bde # gbde init /dev/da0 -i # gbde setkey /dev/da0 -n 2 # gbde attach /dev/da0 # newfs /dev/da0.bde # mount /dev/da0.bde /mnt/usbkey --> use the FS, works fine # umount /mnt/usbkey # gbde detach da0 Then according to the man page I should use : #gbde destroy da0 -n -1 to purge all keys but I get : gbde: illegal option -- n so I changed to : #gbde destroy da0 --n -1 and got : gbde: read: Innapropriate ioctl for device so I changed to : #gbde destroy /dev/da0 --n -1 and this time I get the password prompt but it fails to destroy anything : Enter passphrase: Opened with key 0 gbde: No -L option and no space in sector 0 for lockfile Maybe I didn't understand the purpose of the this command. I thought it was going to replace each lock key with some random data. Can somebody explain me how to use the "destroy" command ? Thanks Dany
