If you just need READ, and not WRITE, howzbout COPY
*.* NUL
actually
XCOPY *.* NUL /S/E
to include subdirectories
But would a red suffice to refresh or do you need to also write?
Also, this solution, and Chuck's, while workable for reads would leave you
with a blank screen for a long time (e.g. xcopying to NUL a 512GB or bigger
SSD).
If I remember Spinrite would read and write each sector back in Level I or
II and gave you a constant update.... I still have a license from long
ago.... I think the last version came out in early 2000s...
