My wife has been complaining about her MacBook Air's performance. It seems to work fine, but when I ran Disk Utility and did a "Verify Disk", it reported filesystem errors. The "Repair Disk" button was disabled, because this is the startup drive.
So, I restarted with the Mac OS X Install Disc and ran Disk Utility again. When I run "Repair Disk", I get this output:
Verify and Repair volume "Macintosh HD" Checking Journaled HFS Plus volume. Checking Extents Overflow file. Checking Catalog file. Invalid node structure. Volume check Failed. Error: Filesystem verify or repair failed.
Is there anything else I can do to try to repair the filesystem (besides erase and reinstall)?
FWIW, here's what happened after I asked this question:
- Restarted in single-user mode (Command-S on boot). "/sbin/fsck -yf" gave more error messages. And when I did "exit", I saw error message "disk0s2: I/O error" followed by "CPU Halted".
- Tried to reboot. Apple logo appeared, and wheel spun for about 15-20 seconds, then machine turned off. This repeated every time I tried to reboot with the internal disk.
- Tried resetting PRAM (Command-Option-PR on startup). No change.
- Called Apple. The expert walked me through SMC reset, which did nothing. Tried to do an "Archive and Install" re-installation, to save original disk contents, but the Installer refused to install on that drive due to filesystem corruption.
- Did an erase and re-install. (And my wife now hates me.)
I'd still be interested to hear if there is anything more I should have done.
