Let us not forget that the GUI tools are merely front ends for the command line tools from cd/DVD record tools. http://fy.chalmers.se/~appro/linux/DVD+RW/ http://cdrecord.berlios.de/old/private/cdrecord.html A system administrator has much more flexibility with command line tools when it comes to automating tasks. > On Tuesday 22 March 2005 09:13 am, Bhaskar, KS wrote: > > Most likely, a DVD connected via a USB port will show up as a SCSI > > device, with a name like /dev/sda or /dev/sdb.

It depends on the linux distribution but most newer distributions recognize USB CD drives as SCSI devices, they are labeled as /dev/scd0 I worked with a Latitude laptop this weekend and installed Debian Sarge and Fedora Core 3, both distros recognized the attached USB CD/RW as /dev/scd0. Your USB mass storage devices, jump drives, cameras, etc. will show up as /dev/sda, /dev/sdb, etc. > > Generally, if you power up the USB drive first, then boot the PC, k3b > > will find and recognize the drive.

Most newer Linux distributions automatically recognize USB devices and make them available on boot. Again, it depends on your Linux distro as to how much work will be involved. > > Mark and/or Crawford may want to correct me here, or expand on the > > explanation, because my understanding of how USB is mapped to SCSI, and > > how CD/DVD-ROM drives are handled on Linunx is shallow. There is some difference how CD/DVD devices are handled in the version 2.4 Linux kernel and 2.6 version, especially USB devices. 2.4 kernel has a SCSI emulation layer that was rather clunky, ide_scsi which allowed IDE devices to emulate SCSI devices, Linus didn't consider the interface elegant so it was reworked in 2.6. There are some hard feelings on both sides between Linux and the author of cdrecord.
