Assume I have some important (big) archives with a size of e.g. 100 MB
(or bigger). I want to burn them on CD/DVD but want to add some safety
features.

That means that if the CD/DVD gets accidentially some scratches
I want to be able to read resp. rebuilt the whole archive bach again.
This should be possible even when 1% of the bits are destroyed.

Does ICE ECC help in such a situation ?

Does ICE ECC add some extra information (extra bits/bytes) to a file
(how much ?) so that the contents is (partially) redundant or is there another system behind it ?

Thx
Peter

ICE ECC add nothing to data file. ICE ECC create additonal .ecc files, like any archiver do. This is files store ECC codes, witch can recover damaged part of original data files.

You can specify any size of ECC files as you want. But for CD/DVD storage i recommend at least 20%-30% redundancy.
