My experimentation led me to:
/dev/hda4: main HD
/dev/hdb: CD-ROM (using ide-scsi)
/dev/hdc: CD-RW (using ide-scsi)
/dev/hdd: Old WDC2850 HD used for transferring files from Linux to
Windoze
/dev/sd{a,b,c}: SCSI HDs
Burning from any of main HD, CD-ROM ("on the fly"), or SCSI HD works
fine. Burning from /dev/hdd is possible at 1x, but I never want to do
that anyway. /dev/hdd is there because one day after writing some
files from Linux to my Windoze partition /dev/hda1, I booted Windoze
to find the root directory and FAT trashed. I didn't particularly want
to experiment to find out why, so now I just use a sacrificial HD.
Why are some CD-ROMs fussy about being the slave, given that the
subservience implied by the name does not actually exist in the
hardware? Some WDC2850 HDs (not the one above) are like this too.
