Kdd process


While copying files (images) from iMac to Home Duo drive, the process hdd is very active and is using a very significant part of CPU capability. The process is identified as a WD process. What is it doing and why is it using so much capacity even after copying is finished?


KDD is the process that runs when you sign in to MyCloud.com via WD Discovery and the My Cloud Home network drive is mounted to the macOS. KDD will use CPU and Memory when accesing the MCH in Finder.


Thanks. But what is it doing and why does the process use so much CPU capacity? It effectively cripples the machine.


I am also experiencing this issue. The KDD process consumes 93% of the cpu (4.2 GHz Intel Core i7) and fails regularly when uploading files less than a gig. I am uploading wirelessly on the same network as the device. Any guidance on how to fix this would be great. Thanks in advance.


Additionally I have noticed that when I drag and drop files from my local machine to the mycloud.com dashboard the KDD process consumes 0.2% of the CPU processing power. This issue seems to only occur when dragging files from one finder window to another. I have tried uninstalling and reinstalling the WD Discovery helper app, however the results are the same. The finder transfer stalls out and the upload fails. Could it have something to do with an APFS/SMB transfer issue?


WD Staff. Could you answer my question?


@Lydnian I would recommend opening a case with Tech Support with make, model, OS, WD Discovery and Desktop App version, how many KDD processes are running, how many folders are activated for Desktop Sync, or if Sync is not used at all, content type (IE: documents, RAW images, CAD files, etc…)


I also suffer this as well. CPU reaches 300%, and the file transfer fails. KDD must be killed and restarted, and the transfer restarted. Seems to particularly sensitive to certain folders / files (can transfer multi-gb of one folder / files, but failed on only 100mb of another).

It’s extremely frustrating - it has taken my days to transfer the content of my old drive to My Cloud Home drive.
