Hello!
I finally got to opening a DVD I received for New Year and wanted to back it
up before watching.
I mounted the disk:
/dev/acd0 on /cdrom (cd9660, local, read-only)
and I can list the contents:
env LANG=C ls -l /cdrom/
total 8
dr-xr-xr-x 1 root wheel 2048 Oct 6 2005 audio_ts
dr-xr-xr-x 1 root wheel 2048 Oct 6 2005 jacket_p
dr-xr-xr-x 1 root wheel 4096 Oct 6 2005 video_ts
But when I try to copy all that to a hard-drive, I get a ton of read-errors --
most of the many files on the disk are unreadable:
...
g_vfs_done():acd0[READ(offset=4623824896, length=65536)]error = 5
acd0: FAILURE - READ_BIG ILLEGAL REQUEST asc=0x6f ascq=0x04
g_vfs_done():acd0[READ(offset=4623828992, length=65536)]error = 5
acd0: FAILURE - READ_BIG ILLEGAL REQUEST asc=0x6f ascq=0x04
...
``dd'' refuses to read from /dev/acd0:
dd: /dev/acd0: Invalid argument
cat tries to, but fails:
cat: stdin: Input/output error
Is there a step I'm missing? I strongly doubt, the disk is damaged, as I just
unwrapped it myself...
I'm on FreeBSD/amd64 running 6.3 as of Dec 30th. The DVD-drive is:
acd0: DVDR <MATSHITADVD-RAM SW-9585/B100> at ata1-master UDMA66
Thanks!
