Windows 10 XCOPY and ROBOCOPY have different destinations--why?

Before letting chkdsk make changes (it goes into long mode), I should back up my hard disk. Acronis always aborts before the "last segment" -- presumably because of hard drive issues.

THEREFORE I tried to use Windows to "clone" my disk.

xcopy C:\*.* F:\ /D /c /k /y /i /e /h /r

To catch files that might have been skipped, I next ran

ROBOCOPY C:\ F:\ /S /IA:HRA /MT:20 /TEE /LOG+:F:\ROBOLOG.TXT

which in the log file became

Source : C:\
Dest : F:\
Files : *.*

Options : *.* /TEE /S /DCOPY:DA /COPY:DAT /IA:RAH /MT:20 /R:1000000 /W:30

------- I immediately recognize I need to use /DCOPY:DAT instead. I want everything to be like the original.

=========== NOW THE PROBLEM:

Overnight the ROBOCOPY version overran the hard drive and was displaying the "disk full" message in rapid succession. Upon inspection, Drive F: directory looked like drive C: directory EXCEPT that in F: the folder Users appears twice. Hence almost everything is duplicated. Furthermore, inside the SECOND copy of Users, the "Documents" folder appears twice. Those two seem to be identical. (I spread my work to subject matter folders, so my "Documents" folder contains VERY LITTLE.)

I am puzzled by the duplications. It would be possible to reformat the F: drive and start over, but that doesn't help if I don't know how to avoid this error in the future. I often use ROBOCOPY on a clearly defined smaller folder. It seems to be a great updating method for the LIMITED range. I wonder how it would work on the entire drive if I do not use XCOPY at all. Is ROBOCOPY the better choice for what I am trying to do?

Also: Acer has a bootable rescue disk option that formats the destination drive. Should I perform that operation first and THEN proceed with the above plan? Would that give me almost the same as a "clone disk" option in case the chkdsk results are disastrous?

By the way, DiskGenius found no errors on C: -- the tested cylinders were all in the top two classifications. The report concluded at 74% for unknown reason. Did it omit blank areas, or do problems lurk undetected?
