WD_Black 12TB keeps activating/deactivating (sleep mode issue?)

Hi,

I am new here and I hope, I have the right Forum: I recently bought a WD-Black 12 TB, but not for Xbox but my Macbook Pro M1 Pro (MOS Monterey). The Drive is shutting down after a few minutes of not being used. It doesnt disconnect all the way, but when I want to use it again, It tages several seconds to start spinning again, I can hear that. This can happen when I just use (pause using) it in the Finder or Davinci Resolve for example. Also weird is, that it sometimes “wakes up”, when I am not doing anything with it.

Is that the sleep mode? My research regarding that didnt help. Also the WD-software for calibrating external drives seems not to work for the WD-Black. Or is this drive really just made for Xbox and not for Computers? It is really annoying though, so thanks for any help or idea!!

Hi @Nisem ,

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!
