Hello,
I just noticed (via Activity Monitor) WDSecurityHelper taking about 95% of my CPU during a Time Machine backup.
I had installed the WD Security app to try out the encryption briefly when I first bought the disk, but disabled and uninstalled it when I figured out my Mac could handle encryption itself.
The WD drive is now encrypted (via Disk Utility), so I would expect copying files to be a bit slower than usual. But I used encrypted disk images under Snow Leopard and never noticed a CPU hit.
Furthermore, the massive CPU usage persisted in Activity Monitor even after Time Machine finished. I closed all apps and applications, emptied the trash, but it was still there. Couldn’t eject the disk either without logging out.
So, if anyone has suggestions, I would be grateful:
-
What is WDSecurityHelper doing, if it is no longer needed to un-encrypt the disk?
-
Why did it stick around after the un-install?
-
Why is it using so much CPU?
-
Or does my Mac just coincidentally use something called WDSecurity for encryption, and this has nothing to do with my WD drive?
-
After submitting a support case, do I typically get an email reply? I didn’t get a confirmation saying “We’ll get back to you in x hours,” etc. The case is in MySupport tab, but no response.
Thanks in advance!
WD My Passport 3TB
