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! -mi
