It occurs to me that maybe CentOS 4.5 wants to handle my CD-ROM as a SCSI device. Is that done with plain old CD readers? This Sanyo CRD-S372B is far to old to actually write CDs and would probably burst into flames if I put a DVD disk into it.


I can't answer the 4.5 specific aspect, but in fact all ATAPI devices (CDs,, etc) attached to ATA/IDE use the SCSI command set, unlike IDE/ATA hard disks, which use the old WDC1003 'commands'.

I think it is because we have a newer libata and are now using the drivers from libata by default instead of the 'old' ide drivers.
