I have a LaCie 4x USB external cd-writer ( MITSUMI CR-4804TE 3.0D ), and Mandrakelinux 10.1 Official, it can burn audio-cds and ISO images that I download from the internet but if I want to burn a data-cd it says that it was successful but the cd doesn't work on Linux and on Windows. I often use both Rockridge and Joliet as extensions with K3B and I think it's due to these. I also tried to open the CD with ISOBuster ( Windows) but it didn't worked. Please show the logfiles and test that I should do to understand the problem and help me if you know.
The second the problem is that I can't add a session to a multisession disk even if the drive is mounted, K3B crashes after this.
