WD My Book Duo - Ejects itself -> Blinking yellow light

Hi guys,

I have been using a My Book Duo 20 TB for a year now, no problems.

Today I plugged in the external harddrive to my iMac, and it ejected itself, and went from a white light to a slow blinking yellow light.

I tried to plug it in again, and the same thing happened.

Anyone have a clue of what the problem? and most important of all… Can I rescue all the material on it?

Kind regards Carl with no backup

Hi,

You should try contacting WD’s Technical Support about this for live assistance and troubleshooting:

To resolve the hard drive auto-eject issue, tweak the power management settings of Mac, as shown here:

• Go to Finder > Applications > Utilities > Terminal.
• On Terminal, type “pmset –g | grep disksleep” and hit Return.
• Check the value of disksleep. If it is low, provide a significant number.
• Type “sudo pmset –a disksleep #” (here, replace # with a suitable number) and hit Return.
• Provide the admin password when prompted.
• Check the changed sleep value using the “pmset –g | grep disksleep” command.

The above solution will fix the drive auto-eject problem. Now, use the hard drive to save and access data as usual.

Cheers!
