I thought these tools bypass the filesystem and make a bitwise copy. dd is fooled, it finishes but just produces a small file and states it's finished. dd_rescuse and ddrescue are complaining about read errors and are intolerably slow. These tools can copy only a few MB in 10 minutes. Why is this happening, why are these tools failing? AnyDVD makes

They make no assumptions about the format of the data and try to maintain the integrity of the whole of the original on disk data. In the case of dd I suspect that it is terminating due to an intentional read error on the disk that is part of the copy protection scheme. It would help to confirm this if you included the commandline output from dd with your question. You may also find some read errors recorded in the dmesg command output. You may get dd to copy more of the file by passing the noerror flag to it on the commandline. However you may find that this just leaves you with corruption in your final image. share|improve this answer answered Feb 24 '12 at 15:00 Richm 2,6141210

Dd Input/output Error
Input/Output error copying files from CD/DVD Try to duplicate your dvd via dd. Suppose your DVD drive is /dev/sr0, then you should execute something like dd if=/dev/sr0 of=dvd-image.iso, where dvd-image.iso - name of image file (note that http://unix.stackexchange.com/questions/32564/why-cant-i-copy-my-dvd-with-dd it will be about 4,5 GB large) . If it fails immediately, then looks like disc is badly corrupted. If not, then wait till command completes, and try to mount this image with mount -t udf dvd-image.iso /mnt (/mnt can be replaced with other mountpoint). Sometimes image mounts better than source disc.

Kosmonavt, it's a data DVD with video files in it, not a film DVD ; also, I can play the videos from the disc normally.

Haven't seen any for a long time. The method I described works (AFAIK) only for DVDs with data - one time it helped me to read a scratched DVD with some backups You really should try method with image. If it don't mount, unfortunately there are almost no free software that can fix filesystem.

However, I've discovered some errors in some of the DVDs through playback e.g. VLC player would just stop playing the iso file when a bad section in playback is met (half-way through a film). The worst thing is that no errors or warnings were thrown during the ripping process - I could have . Is there a method or input output error application that will monitor DVD/file data integrity and avoid such scenarios in the future? Anything equivalent to Exact Audio Copier or CDparanoia for DVDs? dvd iso share|improve this question asked Jun 7 '12 at 14:16 johnnyturbo3 291246 3 I believe EAC and cdparanoia are needed for music CDs because CD-Audio doesn't include the error-correction data in higher-level formats like DVD-Video. It should suffice to just copy the bits directly, as Neojames suggests. –Mechanical snail Dec 19 '12 at 0:21 1 @Mechanicalsnail That's not correct, the encoding of a CD has functionality like parity, but there is also functionality in a drive to read a CD less accurate which EAC and cdparanoia disable or force the drive to verify the read data to get accurate results. –LiveWireBT Dec 15 '15 at 17:31 add a comment| 9 Answers 9 active oldest votes up vote 41 down vote I think you can use dd to copy disks well. Using dd if=/dev/cdrom of=image_name.iso I can confirm it works well with CDs and should work well with DVDs too.

optical disc, retrying until they recover every possible file. The leading tool is probably Isobuster, but there are dozens of candidates for the title. There are few automated (or even user-friendly) data recovery tools on Linux or UNIX(tm) platforms, but common tools which are often even included with the core system or which are installable through the official package system are often sufficient for performing this critical task. One particularly frustrating way to lose data is by burning it to an optical disc and storing it. One often attempts to preserve data this way, only to have cheap media or a cheap storage container (especially binders) destroy the disc beyond repair. Sometimes, however, the data around the error (or at least up to it, which is sometimes still better than nothing) may still be readable if you use a tool more complicated than the 'cp' command (or selecting and dragging files in the file manager of your choice.) Copying an entire disc One excellent starting point is to use GNU dd (from GNU coreutils) or other, similarly capable implementations to recover the data on a damaged optical disc (though perhaps not one so damaged as the one on the right.) A handful of the available options are especially helpful. Here's a possibly excessive example command line for copying a whole disc: dd if=/dev/sr0 of=image.iso bs=2048 conv=noerror,notrunc iflag=nonblock dd is an exceptionally useful utility. The GNU dd manpage says of dd that it will "Copy a file, converting and formatting according to the operands." We don't do any conversion, but we do specify some options as to how to go about reading the data: From my first cd-rom drive (if=/dev/sr0) I read to an appropriately named ISO file (of=image.iso). I specify a block size (bs=2048 means 2048 bytes, or 2 KiB) and some options (conv=noerror,notrunc): noerror causes dd to continue after a read error, and notrunc will avoid any automatic truncation of the output file. iflag=nonblock sets an "input flag" that causes dd to use non-blocking I/O, which should minimize the impact on your system at the possible expense of speed during the copy. Since I always
