I love how easy it was to set this up for my Mac and use it as a way to back up all of my wildlife photographs.

Unexpectedly ejects all the time

Maybe a year after buying, it began ejecting. Support couldn't fix the problem. They replaced it, but that one started ejecting, too. I've tried all the suggestions to fix the problem. Not worth the hassle. At all.

This is not what you think!

I ordered this wd 16tb raid unit to replace a failed 12tb wd my book duo raid unit. After much more research, much to my dismay, despite the settings to mirror the drives, THE DATA WAS IRRECOVERABLE , by me, wihout large expense.These wd raid enclosures use AES hardware encryption that helps prevent unauthorized access. That means you, the owner of the data. If the enclosure fails, as appears they too frequently do, you are out of luck. This is hardly a good solution for data safety. Be aware the AES hardware encryption that helps prevent unauthorized access cannot be user selected as it should be. It is reliant on the circuit board in the enclosure. BTW, wd cannot see fit to sell replacement enclosures. A bad choice for data security and I'm returning the package from BH unopened. Incidentally, the two original 6TB drives still work fine albeit after a reformat which erased all my archived data.

Your hard drive keeps telling me I have a problem with the RAID configuration and there is nothing wrong with it! Very frustrating, AND this on top of one of your Element 10TB drives losing a password and therefore I LOST ALL MY PHOTOGRAPHY!!! This may well be my tenth and final WD Drive ever...
