dvd error... "mount: not a directory"

["tom.lobato" <tom.lobato@terra.com.br>]

  Hello!


  Im writting backups to dvd rw with the command line:

  createfilelist.sh | cpio -o | mkisofs -stream-media-size <N> | growisofs -Z  /dev/scd0=/dev/fd/0

  If I use N = 333000,  It burns the cd normaly so I can mount it on linux or read it from windows later. But, If I use bigger numbers, like 2295104 (the real sectors number of my 4.7GB media), it burns without error messages but when I try t omount it on linux:

  # mount /dev/scd0 /mnt/dvd/
  mount: not a directory


  Some hint?

  (growisofs 5.11, mkisofs 2.01, linux 2.4.20)



  Thank you
  Tom
