i dug into this a little further and it appears that this only happens with
CD-Rs. using CD-ROMs, DVDs or DVD+Rs this doesn't happen. i tested this with
CD-Rs recorded under windows and freebsd (created with burncd(1), growisofs(1)
and cdrecord(1)) and they all suffer the same issue.

i also tried this with audio cds and here recoverdisk(1) fails no matter, if
it's a CD-R or a CD-ROM:

otaku% recoverdisk /dev/cd0 ./test10.iso
Bigsize = 1048576, medsize = 65536, minsize = 2048
        start    size     block-len state          done     remaining    % done
            0 1048576     243052544     0             0     243052544   0.00000
0 1048576 failed (Device not configured)

cheers.
