Q: Can't restore files from damaged hard drive in Disk Utility

Questions

1. Can I save my files/fix this issue without having to restore via Disk Utility?

2. What am I doing wrong/can I do to correctly restore to an external hard drive via Disk Utility?

 

Background

Last week when I turned my 2012 MacBook Pro on I got stuck on the grey login screen. The progress bar moved very, very slowly and when it finished my laptop spontaneously restarted and repeated the same thing over and over. Here's what I've tried to do so far:

 

-Boot in Safe Mode: doesn't work

-Apple Diagnostics/Apple Hardware Test: Extended Test Results: No trouble found

-Disk Utility (recovery and Internet recovery): Mac hard drive (Apple HDD) and Recovery HD (partition) are not damaged, but partition disk0s2 is (created after a failure about a year ago; not Journaled- if that matters) and when 'verifying' and 'repairing' the latter I receive inconsistent error messages.

 

Disk Utility Error Messages

Most often I get this error:

The volume disk0s2 was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk.

Disk Utility stopped verifying “disk0s2”

 

The volume disk0s2 could not be repaired after 3 attempts.

Error: Disk Utility can’t repair the disk. Back up as many of your files as possible, reformat the disk, and restore your packed-up files.

 

I also received this error message once:

Incorrect number of extended attributes (it should be 730585 instead of 730589)

Incorrect number of access control lists (it should be 1364 instead of 1368)

 

Save Files to External Hard Drive?

Prior to this I had not yet used/accessed Time Machine.  I have a new external hard drive, formatted for a Mac. I created two partitions: Backup and Time Machine (so I can start using it once I figure this current issue out). When I try to restore disk0s2 to the external hard drive I get a Restore Failure error message (252 or 254, I think).

MacBook Pro, OS X Mavericks (10.9.4)

    I am not following what you are saying. I want to be sure we are talking about the old, damaged drive.

     

    I wanted to know what the permissions on the files inside the folder:

     

    /User/<your-old-id>

       ... folder were. There should be

    (single-person-Icon) account-owner-name | permission ... this is the Account Owner

    (two-person-Icon) group-username | permission ... this is the Group that has direct access to this file

    (many-person-Icon) everyone  | Permission ... this is the rights of  Everyone (regardless of user-ID)

     

    In the folders above, you did not report what is listed for the file Owner. This is sometimes reported as the word "You" when your current logged-in Account is the Owner, and sometimes System or another User-name.
