Storage Space shows "reduced resiliency" warning, build 14393

Cbarnhorst · 23 Oct 2016

(Dell XPS 8500, 24GB, 1GB mSata system drive, two Toshiba USB3.0 attached hard drives)
I have a storage space set up on my Windows 1607 primary computer. (Storage Spaces is a feature of Windows 8.1 and later and Server 2012 and later.) It is set up with a normal pair of large capacity hard drives and is in two-way mirrored configuration, formatted ReFS. I see the "reduced resiliency warning" but both drives are marked as "OK." What is the meaning of the "reduced resiliency" warning and what is required to remove it"? I get the same warning with a similar storage space configuration on my test box, the only difference being that it is formatted NTFS.

Hi,

In the links following the recommendation is- perhaps rather oddly- effectively to test the drives on another PC.
I guess I might try checking their SMART parameters and running a surface scan
E.g. Crystal Diskinfo, Macrorit Diskscanner
