Product: Envy Phoenix
Operating System: Microsoft Windows 10 (64-bit)
After calls to support and getting nowhere, I remembered that this model had a supplemental cache on the Motherboard which is a small circuit board held on by two small screws. Basically this is a type of SSD disk drive. It is designed to speed up access but many hybrid disk drives now include the same type of function directily on the disk. I removed the small circuit board and the problem went away. It made no difference in performance.
