Yes. It fails right away :
bash-3.00# /opt/csw/bin/readcd -v dev=0,0,0 meshpoints=16
f=sol-nv-b38-x86-dvd.test
scsidev: '0,0,0'

Read speed: 11080 kB/s (CD 62x, DVD 8x).
Write speed: 5540 kB/s (CD 31x, DVD 4x).
Capacity: 1 Blocks = 2 kBytes = 0 MBytes = 0 prMB
Sectorsize: 2048 Bytes
Copy from SCSI (0,0,0) disk to file 'sol-nv-b38-x86-dvd.test'
end: 1
addr: 1 cnt: 1
Time total: 1.096sec
Read 2.00 kB at 1.8 kB/sec.
bash-3.00#
Looks like 1 sector of 2048 bytes of data.
