I tried dump with the following arguments
-a force to the end of reading
-b 2 2kB block size
-f .. write output to file
/dev/cd0a file to read
This is what I got.
bash-2.05b# dump -a -b 2 -f filename.iso /dev/cd0a
DUMP: bad sblock magic number
DUMP: The ENTIRE dump is aborted.
I also tried without the -a and -b options. Same deal.
