Can you see which size of a single write succeeds with that volume?

Also, could you see how many bytes did it succeed to write before the
failure?

The MS-Windows version of copy-file doesn't use WriteFile.  It uses
CopyFile.

Anyway, how did you use copy-file?  Was the source file on the same
CIFS volume, or was it on a local disk?
