If I use move /v to move a file to a DVD, I often get the message "File verification failed", but when I then compare the two files use FC, it says the files are identical. Any idea why this is happening? The DVD is formatted by Windows.

I presume it is a TCC feature that when verification of MOVE fails, it
does not delete the original, thus allowing you to use FC. You could also
use TCC's @compare[] function, regardless, I suspect the issue of
verification vailing when moving to a read-mostly device, such as a DVD, is
due to the delay between delivering it to the Windows driver which actually
writes it, and when it is available on the target DVD. Did you try what
happens when you use COPY /V to the same target?

That definitely won't work with DVD-R, though it might with DVD-RW. The
verification is being done by Windows, not by TCC.
