-69845 'File system verify or repair failed' (1TB WD Elements SE external hard drive, Macbook)
My external hard drive no longer appears in Finder, and in Disk Utility appears greyed out. When I attempt to mount it using Disk Utility, I get an error message reading:
'Could not mount "[my hard drive". (com.apple.DiskManagement.disenter error 0.)'.
When I attempted to run a First Aid on it, it reads:
File system exit code is 8
Restoring the original state found as unmounted.
File system verify or repair failed. : (-69845)
What exactly does this mean, and is there any way I can repair or otherwise access the disk?
