iMac running Sierra. MyBook 8TB desktop raid, formatted for Mac with two mirrored 4TB partitions. It appears in the finder twice, sometimes three times (see attached). Only one of the appearing drives is browsable; the others show the correct amount of free/used space, but no actual files.
The drive does up the same number of times—whatever that is—in Mac OS disc utility. WD Utilities won’t run. I get a “must be in applications folder” message, even though the app is in the applications folder.
