What are "Missing thread recordng" erros when running fsck -fy?
- by ohho
There is some error reported when I run Disk Utility and verify the root volume on my OS X MacBook. So I boot and CMD-S into the shell mode and run /sbin/fsck -fy.
Errors are like:
** Checking catalog file.
Missing thread record (id = ...)
In correct number of thread records
** Checking catalog hierarchy.
Invalid volume file count
(It should be ... instead of ...)
** Repairing Volume
Missing directory record (id = ...)
I'd like to know what is the cause of the above errors? Hopefully I will be more careful in the future to prevent them from happening again.
p.s. I am using a SSD and so I assume mechanical hard disk error is less likely. Thanks!
