Subject: Re: dd if=/dev/zero of=/dev/hda
I have used it to zero entire drives or partitions. generally, zero-ing an
entire drive often takes care of some problems that try to hide in the boot
sectore or partition tables (such as particular worms).

also, zero-ing a drive is much like low level formatting, only without
reqriting the track ID's.

and yes, it will work on just about any FS type.
