How to delete the Other yellow section in Storage

I had about 190 GB of Other which suddenly appeared a while ago. I was able to control it a little through OmniDiskSweeper, OnyX and cleaning/optimizing for a while (I have a late 2011 MBP kept pretty clean and never had this Other stuff before). But still, despite the cleaning, I had about 180 GB and it never went any lower than that...

Then I realized I'd never (apart from OnyX telling me the disk status had to be fixed) repaired the HD/permissions. I thought it may be due to that, so I used the Disk Utily application to verify and repair both permission and HD, came out permissions were all messed up and the HD itself had issues too. As soon as it was repaired the Other was gone.

This is just to help all of those people who have been wondering/trying, with no success, to delete/reduce the Other section in their HD storage. Because I'd never read anywhere that the solution could be to just run Disk Utility. I don't know if it works for everyone, if I was just lucky, no idea... But it did the thing for me! I can finally transfer all of my audio back from the external mobile HD I was forced to purchase a while ago. 🙂
