'Sector structure protections'

When looking at titles that I suspected had this protection, I found a different protection that checks the same sector structure and is also commonly used.

Again, no idea who wrote it or what it's called. It has no identifying text it in. It's a bit simpler as well, it just reads a data and header block length along with the leading and trailing byte before the sync mark, then reads a few more sectors and checks that they match what was previously read. Mostly Mindscape used this one.

Due to its similar nature, this one also gives Vice problems.
