Anyone ever truly WIPED their 5G iPod?

I'm having several problems with my 80GB iPod ( 80GB iPod Video formatted FAT32 for PC synchronization.) My thought was that before I turn it in for repairs/return I would wipe, reformat, and restore. When I say "wipe" I mean to truly, forensically WIPE the drive (i.e. overwrite every sector with zeros.) Then I got to thinking... although this thing is just a hard drive there may be some proprietary Apple boot sector on it that if wiped will make the iPod useless. Anyone have advanced knowledge on the iPod physical drive layout?
