ICE ECC is described as 'ICE ECC is a file verification and repair tool. ICE ECC allows you to protect your important files and sensitive data against digital corruption using Reed-Solomon codes'. There are four alternatives to ICE ECC for a variety of platforms, including Windows, Wine, Android, Android Tablet and BSD. The best alternative is MultiPar, which is free. Other great apps like ICE ECC are Par-N-Rar (Free, Open Source), DataHealthCheck (Free, Open Source) and ParPar (Free, Open Source).
DataHealthCheck is a portable app to check your files for corruption or display their md5/sha1 hash. It is faster than other apps because it checks for corrupted files and update hashes of changed files in one pass.
ParPar is a high performance, multi-threaded PAR2 creation tool and library for node.js. ParPar does not verify or repair files, only creates redundancy. ParPar is a completely new, from ground-up, implementation, which does not use components from existing PAR2 implementations.
