Rescuing optical media can be difficult, due to the many incompatible formats and copy protections that were used. CDs are difficult to image at low-level because most drives do not give access to the raw data.

The following is a table of some available disc dumping tools.

  • In most cases you can just create an ISO image with k3b.
  • Using ddrescue (ddrescue -b 2048 -n /dev/sr0 image.iso image.log and so on) you can make an exact copy of any DVD/CD; intentionally corrupt sectors will just be replaced by zeros. [10] You then need to remove encryption (including region protection) with dvdbackup. [11]
  • Some people report good results with k9copy, not available in all repositories.
  • See also this blog post which covers the preservation of CD-ROMs and DVDs using the readom, ddrescue and cdrdao tools, and audio CDs using cdparanoia.
  • The omimgr tool is a simple GUI-based tool for recovering data from CD-ROMs and DVDs. It wraps around readom and ddrescue.
