A few days ago, I got my Macbook Air battery changed at an Apple store. Since then, about once a day, I've had a "kernel panic" crash, which seems to happen randomly while I'm working. (I've never seen this before.)
I did an extended memory test, which showed no problems, but a disk test on the built in 128 Gb SSD showed these errors:
Checking catalog file.(It should be 67667 instead of 67668) Invalid directory item count(It should be 38 instead of 37) Invalid volume free block countFile system check exit code is 8.
The popup advised repairing the disk using the Recovery HD (Command R on startup). I've done this, but, from the recovery screen, the disk shows no errors, and Verify says the disk is fine. When I rerun the disk check inside OSX, the same messages pop up.
Any idea what's going on here? Is it possible that the hard drive was damaged during the battery install?
