Volume corrupt and needs repair

Hi All,

I ran First Aid on my iMac after installing El Capitan and it is telling me:

"The Volume "X" was found corrupt and needs to be repaired.

File system check exit code is 8

Operation successful."

I've run this a few time with the same result.


How do I repair the volume?

Thanks,

P

iMac, OS X Mountain Lion (10.8.5), null

Restart in Recovery Mode.


When you hear the boot tone, hold the command and R at the same time until the grey screen comes up.


You will see the macOS Utilities come up.


Select the Disk Utility -> Continue


Select the Mactintosh HD, then click on the Umount


Run the First Aid -> Run


Expand the indicator for Show Details. Watch for the File system check exit code is 0.


If the exit code is anything but 0, ReRun First Aid.


After successful First Aid repair, click on Mount to remount the Macintosh HD.


Quit Disk Utility


Restart you Mac

I had this exact issue with my MacBook Pro too on Sierra 10.12.2. And while using Disk Aid in recovery I got operational issues and First Aid failed, so I thought my next step was going to clone my mac and go for a clean install. Then I thought what the heck why not see if there is an update I can try first.


Sierra 10.12.3 was available so I did the update and ran First Aid and bam! No issues. Just to be sure I ran Disk Utility in Recovery and sure enough no failure.


I don't know if I was just lucky or what but trying the update can't hurt.

thanks for posting this step by step. while running the first aid I noticed that the first couple of times i initiated it, it would say "fail". during my 4th attempt, everything was ok and repaired. after restarting the computer i went back to utilities and ran first aid again just to make sure the Volume Corrupt message didn't appear again. thankfully, it did not. once again, appreciate your help.

If Disk Utility doesn't fix the problem you should look at a 3rd party utility like DiskWarrior or TechTools Pro.


Disk Utility is reasonable for average problems but is is very limited bordering on useless for things such as corrupted Volume directories and the like. There are things that Disk Utility can't fix that DiskWarrior or TechTools Pro has no problems fixing so Disk Utility failing to fix the problem may not mean your drive is dying--just that whatever happened is beyond its ability to fix.
