Q: External Hard Drive Not Showing Up

My external hard drive is showing up on my Disk Utility but not in the desktop or finder. I have tried repairing it but an error message comes up:

 

Repairing file system.

Checking Journaled HFS Plus Volume

Invalid key length

Checking extents overflow file

Checking Catalog File

Invalid Record Count

Invalid node structure

Invalid record count

Invalid node structure

Invalid record count

Invalid node structure

The volume could not be verified completely

File system check exit code is 8.

Updating boot support partitions for the volume as required.

File system verify or repair failed

Operation failed...

 

What should I do? HELP!!!

MacBook Air (13-inch Mid 2013), OS X El Capitan (10.11.3)

A:

The drive may be failing. If you erase the drive and reformat it, it may fix the errors. To save your data try one of the below.

 

Pre El Capitan - Try using Disk Utility/Restore to copy the backup to a new location. Please note that this will reformat the destination partition.

 

El Capitan - Get an external drive with no data on it. Try booting into the Recovery Partition (command - R on a restart) and select the drive in Disk Utility, then Edit/Restore and select your internal drive in Restore from. This will likely reformat the external drive erasing all data.

    Had the exact same problem.  My predicament was that the affected drive was a LaCie 6 TB external drive and I have not other drive with that kind of capacity to back it up to. I used Diskwarrior 4 to rebuild the disk directory and it solved the problem whereas Apple Disk Utilities could not. My data was intact and I could use my external drive as a bootable disk with El Capitan installed. Now I guess I'll look for a refurbished (i.e. Relatively cheap ...) 6 TB drive for backup or Time Machine... Good luck.
