A DIY solution to an invalid node structure problem
Authored by: timcharper on Jun 16, '08 01:29:33PM

I had this issue today. My MBP (Mac Book Pro) wouldn't wake up from sleep, regardless of how many attempts. So, I held down the power button to force it to turn off. Then, when I turned it back on, it would boot and show the spinner for about 30 seconds or so, then just turn off. Several attempts yielded the same results.

I booted from install disk and ran the Hard Disk Utility's "Repair Disk" feature, which failed, telling me that repair was impossible and I had a "invalid node structure" error.

Then, with the drive unmounted, I went to the terminal and ran:


/sbin/fsck_hfs -ypr /dev/partition

(as suggested by "spiralscratch" here on the forum)

It took a while, but it made progress and fixed the invalid node structure issues. I had to run disk repair one more time after, but it ran it's course.

The end result is my MBP is fully functional and booting again! Hurray for console commands.

Tim

Could you please take me through the process of :

"Then, with the drive unmounted, I went to the terminal and ran:

Could you please help me.
