>Description:
When blanking a CD-RW on my Plextor 8/4/32 writer with burncd, burncd
will become stuck in a loop waiting for the blanking to finish.
Unfortunately, the only result that ioctl() returns is zero.

acd_get_progress() in atapi-cd.c is returning zero from
request->u.atapi.sense_data.sksv being zero and not request->error.

FreeBSD 4-STABLE did work with the same drive.

>How-To-Repeat:
