When SATA came around, the developers figured it'd be much easier and much more convenient for everyone to add it into the existing framework rather than write a whole new framework. -8<-------------------------------- But when it comes to /dev/sr* I would rather say that it really is some kind of SCSI drive. Those ATAPI cdroms take SCSI commands on the ATA interface. So it all sums up with that you might be able to find your IDE cdrom, your SATA HD and even some USB drive listed in /proc/scsi/scsi. regards Henrik -- The address in the header is only to prevent spam.
