Hi all,
I'm having a hard time getting my external (USB, Firewire) Plextor
PX-755UF to read any retail DVDs at all. I can read any kind of CDs and
also DVD-Rs. But mastered DVDs are invisible to FreeBSD.
I can not even read a single sector from such a DVD with the external
drive, but it's working just fine with the internal one. It's really
driving me nuts.

The NEC drive can read DVDs just fine (although it sucks).

If I attach the device via Firewire, it's just the same. Perhaps it
requires some sort of quirk? Where should I start looking for debug
output? Which test should I run. Any help would be greatly appreciated.
Bye,

I wanted to just use dd to do it, but dd would fail after a small amount of data was read. If I first played a little of the DVD with mplayer, then dd would work afterwards. It probably had something to do with mplayer whispering sweet nothings to the DVD player. Sean -- sean-freebsd@farley.org

The error is: Outputting to /big/MOVIE/CASINO/CASINO_ROYALE1-1.vob 16MB of 6834MB written (0 %) acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 My work around so that I can watch the movie I rented is to skip over the problem area (probably intensional by Hollywood) vobcopy -b 50m Try adjusting the offset-size to your needs.

I had to do this a couple years ago with a laptop's internal drive. Either that or you need to find a patched firmware to make the drive region free (RPC 1). I wrote 2 simple programs back then to play with this, because I couldn't find anything in the base system. "regionget /dev/cd0" prints out the current drive region info, like: vendor resets left: 4 user changes left: 3 drive region: 2 rpc type: 2 "regionset /dev/cd0 3" sets the drive region code to 3. Don't forget that you can only change the region about 5 times (user changes left field). -------------- next part -------------- #include <fcntl.h> #include <stdio.h> #include <string.h> #include <sys/ioctl.h> #include <sys/types.h> #include <sys/dvdio.h> #include <unistd.h> int main( int argc, char const *argv[] ) { int ret; int region; int fd; struct dvd_authinfo dvd; if( argc < 2 ) { fprintf( stderr, "Usage: %s <dvd device>\n", argv[ 0 ]); return -1; } fd = open( argv[ 1 ], O_RDONLY ); if( fd < 0 ) { fprintf( stderr, "Failed to open %s\n", argv[ 1 ]); return -1; } memset( &dvd, 0, sizeof( struct dvd_authinfo )); dvd.format = DVD_REPORT_RPC; ret = ioctl( fd, DVDIOCREPORTKEY, &dvd ); close( fd ); if( ret < 0 ) { fprintf( stderr, "Failed to retrieve region info.
