How to design a method which not only detects errors in file data, but enables them to be corrected? A tale of Hamming, Reed, Solomon and CDs.
So many different types, from read-only disk image .dmg files, to sparse bundles and DVD/CD-R masters. Which to use, and how to create them?
First release version, for El Capitan to Catalina. And completely free of course.
Other major changes include detailed reporting, and user control over the size of buffer used, bringing big performance improvements.
