My Western Digital is not getting detected which was working 1 week before. Suddenly this was not detected and following is happening after connecting in my laptop (OS X El Capitan 10.11.5)
a) Light appearing on the drive.
b) Hearing sound from the drive.
But not detected. Please help me on this.
Did you test the WD My Passport on another MAC computer to see if it will get recognized? How any partitions does the My Passport have? I am asking you this because if you have formatted the external drive into two partitions in two file systems, you could connect it to a Windows PC in order to check if it will get recognized there.
I also would recommend you to change the cable that you connect the external drive to the MAC as it may gеt damaged.
