Searching these strings from check disk log leads to this:

Possibly indicating it may have to do with installing capstone on linux mint 18.2...

However I may also have tried it on windows not sure... but maybe not.

Could be a problem with git on windows as well.

Or even firefox... I know firefox has audio corruption issues... perhaps it might even lead to file system corruption issues ?1 ;)

Anything is possible.
