I was cleaning my MacBook Pro, erasing all unused files I had on it. After that I decided to erase the free space, so I will have all my files organized and cleaned the "used space". After that I verified the disk that shows the following error:

This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.

The questions are:

  1. My mac will go from scratch, means erase all the programs, files, music, pictures etc?
  2. What if I install Yosemite, will it solve my problems?
  3. If number 2 doesn't solve the problem, are there any steps I should take now?

I'm now backing up my MacBook on time machine, just in "case" I lose it all, and before I erased the free space all was fine!

  1. No your Mac will not reset all you files. It is just maintenance of file system and not your files.
  2. No it will probably not solve your problems. It even can make matters worse on filesystem level. Or just ask you to do the same i.e. Repair Partition.
  3. You should just do what it you are asked — boot to Recovery HD with CMD + R on startup and Repair Main Partition.

Word of caution: It might be that you HDD is failing so do Time Machine backup or other form of backup before going futher.


Personally, I would steer clear of Yosemite for a few more months. Look at all the complaints about it in the App Store review section. I've never seen anything that negative before.

Your disk could be failing, but it probably just lost some linked files. I use Scannerz to test my drive periodically because I'm paranoid, even with Time Machine in place. Testing the backup drive is, FWIW, probably more important than testing the regular drive because if the backup fails you're pretty much sunk.

Like the other poster said, make sure all your Time Machine backups are up to date, then let the system go ahead and try to correct the index files. The errors you're showing aren't that serious but who knows. Better safe than sorry.

If sectors on a hard drive or blocks on an SSD go missing because of damage, indexing problems can happen, but I'm guessing maybe you just had the power go out on you once or twice or maybe the unit got shut down while a write operation was taking place.

Hopefully this won't be a big deal.

Good luck.
