And yet it may have been a side-effect of using a combination of CD-R and a particular CD writer that defaults to turning on the laser in a default mode and burning data in a compatible way (TAO or DAO mode), if the device driver sets up the hardware for writing. You would need to do some digging in kernel space, not "dd". Ancient FAQs on CD writing with Linux have never suggested using "dd", but always "cdrecord", "cdrdao" and similar tools. "dd" has been one method for creating ISO images from CDs as an alternative to "readcd". _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
