Comment 5 for bug 1356528

Hi,

ok, I followed your instructions. First I wrote the larger image with

  dd if=/dev/zero bs=2048 count=400000 | /usr/bin/growisofs -Z
/dev/sr0=/dev/fd/0 -use-the-force-luke=notray -use-the-force-luke=tty
-use-the-force-luke=4gms -use-the-force-luke=tracksize:400000
-use-the-force-luke=dummy -use-the-force-luke=dao:400000 -dvd-compat
-speed=8 -use-the-force-luke=bufsize:32m

and, hu, everything went fine :-), no kernel messages.

Then I wrote the smaller image without the dummy-option:

cat medien/filme/DVD-ABBILDER/show-musikprojekt.iso | /usr/bin/growisofs
-Z /dev/sr0=/dev/fd/0 -use-the-force-luke=notray -use-the-force-luke=tty
-use-the-force-luke=4gms -use-the-force-luke=tracksize:96525
-use-the-force-luke=dao:96525 -dvd-compat -speed=8
-use-the-force-luke=bufsize:32mExecuting 'builtin_dd if=/dev/fd/0
of=/dev/sr0 obs=32k seek=0'

last lines of growisofs again:

As you can see, I didn't have to wait until the drive has stopped
working because growisofs finished itself...

When growisofs told me of that error the kernel bailed out:

At last I compared the disc with the image, they seem to be identical:

dd if=/dev/sr0 bs=2048 count=96525 |diff -

btw., with bigger images the error occurs again, but this is what you
expected, isn't it? E.g. here:

cat videos2013.iso | /usr/bin/growisofs -Z /dev/sr0=/dev/fd/0
-use-the-force-luke=notray -use-the-force-luke=tty
-use-the-force-luke=4gms -use-the-force-luke=tracksize:2075862
