Verifying volume Macintosh HD Performing live verification. Checking Journaled HFS Plus volume. Checking extents overflow file. Checking catalog file. Missing thread record (id = 1399529) Incorrect number of thread records Invalid volume directory count (It should be 130143 instead of 130144) Checking extended attributes file. Checking volume bitmap. Checking volume information. The volume Macintosh HD was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk. So today I was going to run Onyx. I run it every Sunday morning. And the volume test failed. So I check the exact cause in disk utility (posted above). I run TechTools Pro 5 and check my hard drive. Everything passed. My computer is functioning just like it did before this started. Just as fast. No weird HDD noises. etc. So Now I'm getting ready to repair for a second time! It is advising me again... I checked it again just to make sure nothing was wrong, and to my shock, something is wrong again. And it is the same warnings again.
