Wow what a command name! When I first read your msg I had a double take, since wiping (i.e., erasing) /dev/sda4 would erase my entire linux installation. Reading the man page helped, but I would like one more piece of assurance. Am I correct in believing/hoping that when the man page says When used without options -a or -o, it lists all visible filesystems and the offsets of their basic signatures. it means When used without options -a or -o, it lists all visible filesystems and the offsets of their basic signatures *and erases nothing*. I really don't want to damage any "signature" on the extended partition that is needed to access the "sub-partitions" it contains. As I said my newly installed gentoo resides on those sub-partitions. thanks. allan
