DVD ROM Drive confusion
in my box I have a DVD-ROM drive and a DVD burner. I ide-scsi'd both of
them (because I occasionally use multi-session DVDs which, when using
the ATAPI driver, are not mountable any more if the last session is
beyond a certain position). This sould make the drives appear as
/dev/scd0 and /dev/scd1. However, regardless of whether I mount
/dev/scd0 or /dev/scd1, I always get the disk in the DVD burner (hda)
mounted and never the one in the DVD ROM (hdb).
Attached below is the output of dmesg and cdrecord -scanbus, all of
which looks fine to me:
