When using WDE, where does (if anywhere) truecrypt store a backup volume header? As i know there is always a backup header for regular truecrypt volumes, however i am not sure if this applies when system encryption is used.

Because if i damage the volume header in track 0, my password won't boot my system anymore. So there is no backup header on the drive?

I read somewhere on a forum that truecrypt might have a backup header relative to some position from the END of the HDD, however this doesn't make sense as it could easily be wiped over by programs running in Windows. And how would truecrypt know where this backup is anyway?
