Here's how to wipe everything from an empeg hard drive. Note that this requires a working (hardware AND software) empeg to begin with, and the Hijack kernel must be installed.

From any Linux box:

ftp my.empeg.ip.addr
site rw
put /dev/zero /dev/hda
quit


Windows folks will have to find their own methods..

Not recommended for the faint of heart, or the technically disinclined.

Cheers
