Safely remove an external drive connected to Wd My Cloud

how to safely remove an external drive connected to Wd My Cloud on Macbook

Log into the web UI and eject it.

I do’n t understand the web UI

In WD terms, the ‘Dashboard’. See the user manual for details.

Thanks, I found it

If I remove the external drive from my My Cloud, have I lost all data? I read something in the manual, but do not understand it correctly.

No. Once the data is copied to the external USB hard drive it is not deleted or removed when one ejects or removes that hard drive from the My Cloud USB port.

Ok. Thanks
