Thanks. The most recent edition of that old list is probably Macintosh: System Error Codes Explained, archived by Apple.

Please add detail of what was reported by Disk Utility. You may find a record in /var/log/fsck_hfs.log

comment What is Shutdown Cause -108?
Whilst Mac OS System Error Codes: 0 to -261 is archived by Apple, and describes error codes (not shutdown causes), I should not rush to dismiss its relevance. Compare with a recent answer about error code -60, which does appear to correspond with <Debug>: Previous Shutdown Cause: -60

The screenshots that I have seen show License and Warranty – thanks for the question. I have edited the opening post.

comment How can I get back a system file after deleting it from my Mac?
When copying from Recovery OS: caution! It's commonplace for the version of Recovery OS to not match the version of OS X. For example: an installation of OS X 10.9 that is updated to 10.9.2 will be limited to Recovery OS 10.9 (with the SSL vulnerability, and so on).

comment Does OS X sometimes run a lesser-known TRIM routine with drives that are not explicitly supported?
+1 – the hfs_unmap_free_ext distinction and subsequent bullet points are particularly useful. Thanks.

Order. Quotes from the nanosecond stuff and from a response. Preparing to add a bounty.

comment Don't wake up external hard disk when saving to internal one
For all applicable volumes, would you like the option of discreet but distinctive Unmount icons (two arrows, seen in Disk Utility) in both (a) the sidebar of Finder and (b) Columns view at the Computer level?
