Using version 1.0.12 got an unexpected error:

Version 1.0.13 does not send the error, and restarts checking normally...

stressdisk_stats.json

stressdisk.log

Just in case it helps to debug 1.0.13....

This could be a corruption on the disk.

Are you writing the stressdisk.json to the disk you are testing G:? If so it probably indicates a problem with it.
