I got the following output:

Would you be able to explain what these errors mean and whether it means there are errors in the filesystem? I couldn't figure out to interpret these based on the README. Thank you!

Hi, sorry to bother again but I was wondering if you'd be able to help me out here. Thanks in advance!
