Dd Dvd To Iso
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 a second on a Win7 host. It says that the UDF filesystem is use dd to copy dvd patched, curiously, it also says that there are no bad sectors. The whole disc can be copied in 10 minutes.

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 the filesystem and do a "bitwise" copy, and replace the read errors with zero bytes, would that still yield a corrupted image? After all I only re

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 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 that I really need my DVD-ROM. This is what it looks like when there's errors: dd: reading `/dev/sr0': Input/output error
