I just bumped into this program called ICE ECC, which is supposed to generate recovery data from files so as to be able to recover corrupted files from removable media. I'll be trying it out tonight.

Does anyone have comments about this software, or use other solutions to protect stored data from damage or corruption?

Tell me how big are those files......I wouldn't want to have 30 GB of backup data XD

So we're basically talking about an improved PAR? I've never had a problem with corrupted removable media - generally I've only seen this technology used in Usenet postings, where occasional corruption/missing files is commonplace.

I used to do the same thing with par2 files on all my anime DVDs. However, in the years since and with all the discs it has not once saved me. As it turned out, disc errors were never within the correctable range. Either a disc was ok, or too much was bad. I had much better luck reading marginal data using another DVD drive (different brands often have strengths and weaknesses).

I would say, it's worth it if it's fast, convenient, and you have space left over. However, don't spend too much time on it.
