I reseated the hard drives and tried again and now it doesn't turn on at all. Western Digital has announced the 20TB My Book Duo, the company's highest-capacity desktop hard drive ever. If the configuration has issues with a RAID-0 array, it’s easy to see that this makes your data look like it’s been fed through a paper shredder. Reconfigure the drive to RAID-1 for redundancy (data mirroring), or use it as two independent drives (JBOD) with the included WD Drive Utilities ™ ™ software. With personal cloud being all the rage, the Duo delivers on all counts and expands on storage capabilities with RAID1. RAID-optimized firmware is perfect for two-disk array systems with auto management of drive operations to help ensure read/write cycle data integrity. The My Book Duo is a hardware RAID system, meaning its RAID configuration works independently from the host computer.
The system has a USB Type-C port (cables included) and supports USB 3. 1, desktopo win 10, macbook pro latest OS X, imac 21' and 27 '. R7000 sees WD My Book Duo only via USB 2. Ready to use right out-of-the-box with pre-formatted NTFS for Windows® OS users. Wd my book duo raid 1 setup I have formatted it for Mac (Mac OS Extended (Journaled)) but have found that it is not recognised by the included software, WD Discovery so I have not been able to set it up using this.
