My book duo 8tb enclosure failure


I’m pretty sure the enclosure failed on my my book duo 8tb hard drive. I bought it a few months ago and now when I plug it in/connect it to my Mac it can’t be found. I have it set to mirrored raid HFS-J. I’ve tried trouble shooting with different cords and computers with no luck.

My question is: can I put the two drives in a new enclosure and access my files? I have found a page on the WD troubleshooting page that says that’s what needs to be done, but after reading forums and reddit people make it seem like that’s not the case.

Has anyone experienced this or tried putting drives in a replacement enclosure?


Hi Nickbphoto,

The WD My Book Duo Device enclosure comes with 256-bit Hardware Encryption. You can replace the failed enclosure with the same enclosure otherwise the data on the internal hard drive(s) may or may not be accessible when used in another enclosure.

For more information, you can refer the below mentioned link to know about hardware encrypted devices.

Hi Nickbphoto, did you ever try put the drives into another enclosure? My brand new MyBook Duo 8tb failed after less than a week, saying that the data cannot be accessed. It was configured in RAID1 to allow me access to the data in case one drive failed, but I have also come across conflicting information about whether I would be able to read a single drive in a different enclosure.
