>..> acd0: rezero failed
I see this with an HP 8100 burner - apparently REZERO isn't supported.
A hack around it is to use START instead of REZERO. The doc for an
older HP model says those two commands are equivalent.
In sys/i386/isa/atapi-cd.c:
static int
acd_rezero_unit(struct acd *cdp)
{
#if 0
return acd_request_wait(cdp, ATAPI_REZERO_UNIT, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0);
#else
return acd_request_wait(cdp, ATAPI_START_STOP,
1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0);
#endif
}

Try it with just the second (start) request.
