Disk Warrior, or backup/erase/restore are the only two options. No other company has figured out how to rebuild HFS directories, except the makers of Disk Warrior.

Is there any utility I can use to fix Finder (directory) damage or even detect if that is where my problem is?  The long delays that occur when opening a directory are beyond frustrating.  I could not find a free (DiskWarrior lite).

Thanks Again

500MB/s is decent performance for a 4 drive RAID 5.

If you are getting long pauses, that is usually Finder (directory) damage.

Disk Warrior will save you the time for backup/restore. But it is $119.

No, I do not have Disk Warrior

Thanks,  the latter sounds don't sound good.  My only backup is Backblaze.

Its a more standardized test. It should show the same results.

My guess is you have a badly damaged volume directory. Do you have Disk Warrior?

Or you may need to backup/erase (as HFS again), restore/

 This 4 Disk Raid 5 is so slow it is driving me crazy.  It takes a long time ti access the drive.

Please check out the video of the delay in accessing the drive
