I want to store private documents on a dvd so I followed this prescription
dd if=/dev/zero of=loop bs=1G count=2
losetup /dev/loop0 loop
cryptsetup --verbose --cipher "twofish-cbc-essiv:sha256" --key-size 256
--verify-passphrase luksFormat /dev/loop0
cryptsetup luksOpen /dev/loop0 loop
mke2fs -m0 -j /dev/mapper/loop
mount -t ext3 -o rw,defaults /dev/mapper/loop ~/mnt1
cp -Rpv doc/ mnt1/
umount mnt1
cryptsetup luksClose loop
losetup -d /dev/loop0
growisofs -dvd-compat -Z /dev/dvd=/video_1/loop
This all completed without errors
So then I
cryptsetup luksOpen /dev/dvd dvd
mount -t ext3 -o rw,defaults /dev/mapper/dvd ~/dvd
No problems with that
I was able to read the documents on the dvd but there was a 30 second or
more delay
The delay got longer the more documents I tried to read
I descided to unmount the dvd but it would not unmount and locked the
computer so that I had to hard boot it
Where might I have gone wrong
kernel-PAE-2.6.32.11-99.fc12.i686
cryptsetup-luks-1.1.0-0.4.fc12.i686
