Thanks for the clue. I remember "some sort of cmd" that told me
that my second drive was (I thought) 1,1,0... but wasn't abs
certain. Your ``cdrecord -scanbus'' did the trick::
Using libscg version 'schily-0.8'.
scsibus1:
1,0,0 100) 'PIONEER ' 'DVD-RW DVR-112D' '1.21' Removable CD-ROM
1,1,0 101) 'LITE-ON ' 'DVDRW LH-20A1P ' 'KL0N' Removable CD-ROM

1,4,0 104) *
1,5,0 105) *
1,6,0 106) *
1,7,0 107) *
Being new to this burning discs as backup, i didn't want to
risk trying my second burner. (seeing smoke coming from the
drive or whatever... ;) Now I'm set to try.
