DVDISASTER - data loss/scratch/aging protection for CD/DVD media

DVDISASTER provides a margin of safety against data loss on CD and DVD media caused by scratches or aging media. It creates error correction data which is used to recover unreadable sectors if the disc becomes damaged at a later time.

Common usage examples:

-r, --read

Read the medium image to hard disc. Use -rn-m to read a certain sector range, e.g. -r100-200.

-c, --create

Create .ecc information for the medium image.

-f, --fix

Try to fix medium image using .ecc information.

-s, --scan

Scan the medium for read errors.

-t, --test

Test integrity of the .img and .ecc files.

-u, --unlink

Delete .img files (when other actions complete).

Drive and file specification:

-d, --device device

read from given device (default: /dev/cdrom).

-p, --prefix prefix

prefix of .img/.ecc file (default: medium.* ).

-i, --image imagefile

name of image file (default: medium.img).

-e, --ecc eccfile

name of parity file (default: medium.ecc).

Tweaking options (see manual before using!):

-j, --jump n

jump n sectors forward after a read error (default: 16).

-n, --redundancy n%

sets redundancy for error correction (default: 14.3%).

--adaptive-read

use optimized strategy for reading damaged media.

--auto-suffix

automatically add .img and .ecc file suffixes.

--cache-size n

image cache size in MB during -c mode (default: 32MB).

--dao

assume DAO disc; do not trim image end.

--fill-unreadable n

fill unreadable sectors with byte n

--speed-warning n

print warning if speed changes by more than n percent.

--spinup-delay n

wait n seconds for drive to spin up.

--split-files

split image into files <= 2GB.

Graphical user interface options:

--keep-style

do not override the style settings.
