TrueDisc Error Correction for Disc Burning?
An anonymous reader asks: "Macintouch has a link to a new piece of software — TrueDisc — which claims to make data burned to record-able discs more reliable. More specifically it uses interleaved redundant cells to rebuild data should part of the disc be scratched. On the developer's blog they say they plan to create an open-source implementation of the TrueDisc system, now that it is not going to be included in the Blu-ray/HD-DVD standards. Have any of you used this software before, and what alternatives are already available?"
No, you don't understand. The dupes and redundant posts are a required part of Slashdot's backup procedures.
For large data sets, I rar to a "block" size one third of that of my media, then put two data blocks and one par block per disk. Yes, it's a pain to restore, even without damage, but it gives me great recoverability, as I can loose up to a third of my disks and still be able to recover. These data sets are typically 50 to 200 GBs, btw...
