November 2, 20205 yr I have a WD 10tb drive that I previously used with Windows Storage Spaces without any issues. I've just built a new Unraid server and transferred my drives over. Everything went smoothly except for this drive. When I attach it internally to the SATA ports the Unraid server doesn't see it at all. When I attach it using a SATA to USB cable then Unraid sees it, but it will not mount, and when I go into the Self-Test page it says "A mandatory smart command failed exiting. To continue, add one or more '-T permissive' options." Windows also can't read or partition or format it now, only saying "No Media". I've tried everything I know in Windows (chkdsk, diskpart, various formatting and partitioning utilities, etc) but nothing has worked. I don't know enough about Unraid yet to try to fix it without guidance. mediiia-diagnostics-20201101-2320.zip Edited November 2, 20205 yr by emeybee Added diagnostics
