Should I reformat my mac? Getting a weird error.

First of all, my 2012 15" rMBP on Yosemite 10.10.3 runs perfectly fine. I have very small issues here and there but it's rare. Every few months I do repair disk permissions and do a verify disk thing using the disk utility though. I don't remember the last time I actually verified the disk itself, maybe a year or so ago. Anyways, today during my rare check up, it said that I in fact did need to repair the disk, and I needed to restart the computer and go into the disk utility during the restart. Easy enough!

Well, upon running that process for a few minutes, I get this error...

Once again, my mac runs perfectly fine right now. Haven't had any issues. I backed it all up today too so I do have a very recent backup. Is it worth me reformatting the disk and restoring my files if I'm not having issues? Does this error somehow spell doom for my mac or something? Rather confused that it's asking me to perform such a serious task considering things are running well and have been for a while.

Or should I just make sure I make backups pretty regularly and wait for something to actually happen before I reformat?

MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10.3)

How did you backup the disk drive?

To fix the error you are going to need to reformat the disk drive. Once you reformat all the data on the disk drive will be gone so you need a different place to boot from. My usual suggestion in case like this is to create a bootable clone. This can be done with either CCC or SuperDuper. You will probably need another disk drive for the bootable clone.

This error should be repaired. It is a problem with the directory which operating system uses to keep track of your data. If you don't fix it, it can worst and cause the total lose of all data.

Thats good news. I would still make lots of backups & keep an eye on it, if you get the warnings again look at replacing the disk, they don't last forever.
