Hello, So recently I was writing in Microsoft word, and I started getting a weird error stating that the disk was corrupted (I've since tried to replicate the error after restarting to no avail). So I ran disk utility and received an error message saying that I need to repair the disk from the startup utility. So I go to do that, when I click on verify disk for the Macintosh HD, nothing happens, and repair disk is greyed out. When I click 251 GB Apple SSD it allows me to verify and repair the disk, but it states that it's verified and good to go. Any ideas?
