Could you explain the PAR file and why that would help?

  PAR files are a form of Forward Error Correction (FEC) (implemented with Reed Solomon). They can be used to repair some percentage of damaged blocks in a file or set of files. The percentage is determined ahead of time when you generate the FEC (PAR files) and imposes the same amount of storage overhead (i.e., 15% redundancy costs 15% additional disk space with Reed-Solomon). https://en.wikipedia.org/wiki/Error_correction_code#Forward_error_correction https://en.wikipedia.org/wiki/Error_correction_code#Forward_... https://en.wikipedia.org/wiki/Reed%E2%80%93Solomon_error_correction https://en.wikipedia.org/wiki/Reed%E2%80%93Solomon_error_cor...

    CDs already use Reed Solomon, though. But yes, you can double it up.

      33% parity, apparently. https://en.m.wikipedia.org/wiki/Cross-interleaved_Reed–Solomon_coding https://en.m.wikipedia.org/wiki/Cross-interleaved_Reed–Solom...
