Solar EclipseUse this algorithum that uses parity bytes to protect your blocks of data as a backup strategy.

Blue GeneHave you never lost a file because of storage media failure? That is, have a hard drive or USB stick lose a bunch of sectors (bad sectors) that simply happened to be the ones hosting parts (or all) of your file?

vivelafranceAdd Reed-Solomon ECC to files so that they can be recovered from corruption.

The idea behind this process is error correcting codes, like for example the ubiquitous Reed-Solomon. With Reed-Solomon, parity bytes are used to protect a block of data from a specified maximum number of errors per block. In the tools described below, a block of 223 bytes is shielded with 32 bytes of parity. The original 223 bytes are then morphed into 255 "shielded" ones, and can be recovered even if 16 bytes from inside the "shielded" block turn to noise...
