I have a WD My Passport Ultra Hard Disk. I am trying to use it on El Capitan.

Its not showing up in the Finder.

When I open Disk Utility, it just keeps loading forever and does not show any information at all.

I tried rebooting the system, that didnt work.

Then I went to the Terminal. The disk is showing up there:

Amits-MacBook-Pro:~ amit1235813$ diskutil list
/dev/disk0 (internal, physical):
#:                       TYPE NAME                    SIZE       IDENTIFIER

2:       Microsoft Basic Data SANGRAH                 2.0 TB     disk2s2

The disk name is 'Sangrah' - that means its connected but not mounted. So, I tried mounting it but it shows a time-out error:

Amits-MacBook-Pro:~ amit1235813$ diskutil mount /dev/disk2s2
Volume on disk2s2 timed out waiting to mount

It was working fine half an hour back and now its not. Could anybody please help? Thank you!

  • Try "sudo diskutil umount /dev/disk2" followed by "sudo diskutil mount /dev/disk2" (don't specify s2 partition). Also, is the format NTFS, FAT, or ExFAT? Please post results. – NoahL Dec 8 '16 at 7:38
  • Its weird, its mounting now without any issues. This happened last month too. In any case, I will be sure to try what you suggested the next time this issue occurs, which I am afraid it will. – Amit Saxena Dec 8 '16 at 8:56
