Helps recover unreadable sections on damaged disks

'dvdisaster provides a margin of safety against data loss on CDs and DVDs caused by scratches or aging. It creates error correction codes to compensate read errors which are not correctable in the CD/DVD drive. It also reads as much data as possible from defective media; typically, it handles up to 10% unreadable sectors (relative to the overall medium capacity) using its error correction code. Hardware requirements for running 'dvdisaster' include:

-x86 compatible hardware in 32bit mode
-an up-to-date CD or DVD drive with ATAPI or SCSI interface
-at least a P4 at 2Ghz or comparable processor
-file system without the 2GB size limit for handling DVD images
