I bought it yesterday. Overnight I converted it to RAID 1. I haven’t put any data on it yet, but when I run Diagnostic test / Full test it immediately goes to 10% but then seems not to proceed any further. The short test passed ok. I’m running Win 10. The WD firmware is up to date.
When you go to the storage section, are you able to see the status of the drives ?
Yes. Both drives are shown as “Good”.
