I've investigated cdio.c and mmc.c files and here's what I've spotted.
Below are values from mmc.c's while loop in
get_media_capabilities(int *cap) function;
mmc.c: feature == 0 *cap == 0
mmc.c: feature == 1 *cap == 0
mmc.c: feature == 2 *cap == 0
mmc.c: feature == 3 *cap == 0
mmc.c: feature == 1d *cap == 0
mmc.c: feature == 21 *cap == 0
mmc.c: feature == 23 *cap == 0
mmc.c: feature == 2d *cap == 1
mmc.c: feature == 2e *cap == 1
mmc.c: feature == 100 *cap == 1
mmc.c: feature == 104 *cap == 1
mmc.c: feature == 105 *cap == 1
Above function sets *cap to 1.
MEDIACAP_CDRW_WRITE has 0x02 value, so
if ((mediacap & MEDIACAP_CDRW_WRITE) == 0) test in cdio.c file is true.
When I comment out this test my cd-drive blanks with no problem, so I think
that its features are discovered wrongly.
Regards.
