Ddrescue Dvd

up vote 6 down vote favorite 2 I tried dd, dd_rescue and ddrescue, all failed. 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 the disc copyable in dd copy cd a second on a Win7 host. It says that the UDF filesystem is patched, curiously, it also says that there are no bad sectors. The whole disc can be copied in 10 minutes. UPDATE: As for the solution, see my similar question on superuser. filesystems backup data-recovery dd dvd share|improve this question edited Feb 28 '12 at 21:07 asked Feb 24 '12 at 11:21 Ali 90141114 add a comment| 4 Answers 4 active oldest votes up vote 10 down vote accepted I think that the simplest answer is that dd, dd_rescue and ddrescue are not designed to defeat copy protection schemes. 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 Thanks, upvoted. If I bypass t

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 http://hyperlogos.org/page/Recovering-damaged-CDs-or-DVDs-Linux Linux or UNIX(tm) platforms, but common tools which are often even included with the core https://bbs.archlinux.org/viewtopic.php?id=114032 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 dd copy 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 dd: error reading 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 assume that the copy will take a more or less indefinite period of time, this does not offend me at all, but I admit that it also helps to have an external DVD burner lying around as a backup in case I change my mind and decide

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 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.

Sometimes you get I/O error but everything seems fine and the file plays OK.

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.
