Ddrescue Dvd
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 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 replace that data with zero bytes th
