If anybody knows of any ISO 9660 CDROM discs that use
512 or 1024 byte blocks, I would appreciate a pointer to such
CD's or CD images. I want to add support for 512 and 1024 byte
sectors (per the ISO 9660 standard), and I want some disc images
to test against. I want to do this because I have a source tree
CDROM with over 100,000 files in it. Changing the sector size
from 2048 to 512, will save an average of 768 bytes per file,
which comes out to 75 megabytes compressed, 150 megabytes
uncompressed.

Anyhow, any pointers to such images would be
appreciated. I believe I have extended mkisofs to generate
correct images with 512 byte and 1024 byte sector sizes, but
I am not sure. So, I would prefer some outside images that I
could use for testing.
