Hi Gary,
Good call!
On the R710 (running 8.0) with the FreeBSD/amd64 8.0-R DVD image in the
virtual drive:
(501) ~ $ sudo cdcontrol -v info
Password:
Starting track = 1, ending track = 1, TOC size = 4608 bytes
track start duration block length type
-------------------------------------------------
1 0:08.62 144:07.29 512 -662 data
0 0:00.00 - -150 - -
On a different machine (running 6.4) with a real DVD burned from the same
image in the drive:
(501) ~ $ sudo cdcontrol -v info
Password:
Starting track = 1, ending track = 1, TOC size = 18 bytes
track start duration block length type
-------------------------------------------------
1 0:02.00 235:08.05 0 1058105 data
170 235:10.05 - 1058105 - -
Something definitely not right there.
I can try with the same DVD in the internal drive on the R710 tomorrow, just
in case that makes any difference.
Best regards,
Scott
