In-session disk utility finds corruption but recovery mode doesn't?

[UKPoliticsGuy]

Hi,

Macbook Pro Late 2013 user.

When I run disk utility on my main drive it finds corruption and asks me to go on to recovery mode to fix it.

Problem is: I go on to recovery mode, run disk utility and it says there's no problem!

What's going on?!

Running a file system check on a running, mounted file system is not reliable because of caching in the operating system. I would ignore the results on the boot drive when not running in recovery mode.

I see. Thank you!
