Noticed this for awhile, there seem to be some unrelated lines showing up in disk log for drive name /dev/sdd. drives with names other than /dev/sdd are grepping their lines correctly.
Here's an excerpt of the log of /dev/sdd on my system

These lines are probably unrelated but erroneously grepped due to them having 'dd' in their line

It's just a tiny annoyance but would love to see my logs cleanly if it's an easy fix.
Thanks!
