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.
