Somewhat inexperienced at this SCSI setup, but looking at my system the real SCSI CD's are sr0 and sr1. The sr? values are assigned based on the SCSI id number. In fact I recently (yesterday) had a problem adding a SCSI dvd as SCSI id 0 on a system that already had SCSI id 4 and 5 because the SCSI id 4 device had already been linked as sr0. After the new dvd was added as SCSI id 0 the new dvd became sr0 and the pre-existing SCSI id 4 device become sr1. The links did not automatically change and the new dvd assumed the identity of the SCSI device which was sr0.
What I am suggesting is that your SCSI cd system is as follows: /dev/sr0 scsi id 4 42x cdrom /dev/sr1 scsi id 5 cdwriter /dev/scd1 emulation 52x ide cdrom This does not agree with the info that you provided, but on my system the lower SCSI id device gets the lower sr? value. To solve my problem the /dev/dvd and /dev/cdrecorder were removed (rm). Then new links were established for /dev/sr0 -> /dev/dvd and /dev/sr1 -> /dev/cdrecorder. Until these links were established on the system fstab did not reflect the physical system. Having only ever worked on two SCSI systems treat the above comments with caution.
