Hmmm...maybe someone secretly replaced your
crack with methamphetamine crystals...and you didn't notice :)

Seriously, the ISO9660 format only limits you to
a 640MB filesystem if you plan on making a CDROM.

To duplicate a drive you can make an ISO image of *ANY*
size and store that to be used as a mountable "live" filesystem
that is read only and that can be recovered from on the /dev/loop device.

man mkhybrid
spells it out nicely.

So a 6.4GB hard drive can be saved as an ISO image on a 44GB hard drive
for later use.

bad example:
mount /dev/loop /saved/6.4GB.iso -t iso9660
cd /dev/loop0
find . -depth -print | cpio -pdumv /newfilesystemdiskmountedhere
rm -fr /newfilesystemmountedhere/[ the RockRidge crap ]
boot from recovery floppy
lilo
