Keep udev updated!!!! I don't trust hald and hence service haldaemon stop when I want to write DVD's otherwise I get coasters ! No zip hardware to test your exact problem though Cheers John FC3 on i386 and x86_64 Dr John Austin, email ja +at- ee +dot- port +dot- ac +dot- uk ja +at- jaa +dot- org +dot- uk
