On my laptop, when I do: $ cdrdao scanbus
, I get the following output: -------------------------------------------------------------------------------- Cdrdao version 1.1.9 - (C) Andreas Mueller <[EMAIL PROTECTED]> SCSI interface library - (C) Joerg Schilling Paranoia DAE library - (C) Monty Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables.

On both machines Debian 3.1 is installed. Please, any suggestions about what the problem could be with the laptop?
