I'm using robocopy to copy files from a CD drive to a SATA drive in USB-to-SATA enclosure. This is the command that I'm using:

FOR /F "tokens=6" %%a IN ('vol e:') DO SET var=%%a
md k:\%var%
robocopy e:\ k:\%var%\ /s /XO /R:1 /W:1

The files seem to be copying OK but I am getting alot of these errors:

ERROR 87 (0x00000057) Time-Stamping Destination Directory
...The parameter is incorrect.

Any idea what this means, and what might be causing it?

I'm running Windows 10 Pro 21H2

If you are copying to FAT, then add the /FFT parameter to assume FAT file times (2 second granularity).

You could also try using the /COPY:DT parameter. By default, robocopy copies data, attributes and timestamp, and this parameter will skip the attributes.

Try also with /copy:dt /dcopy:t.

If the file systems on the source and target are different, for example NTFS and exFAT, it would be better to use xcopy for copying.

Question: Do you have funny dates, like far in the past/future, for some of your files or folders? You will find the name of the file or folder listed in the error message.

A workaround that worked for some people having this problem is to copy the directory structure first using xcopy.

Example:

xcopy /t /e "FROM" "TO"
robocopy.exe "FROM" "TO" /mir /R:0

  • The source (the CD drive) is CDFS. The target drive is NTFS. I've just tried adding /copy:dt /dcopy:t but got the same errors. I'm using robocopy rather than xcopy because I'm getting quite a few CRC errors etc on the optical discs that I'm copying and I want them to be skipped over.

  • In case of errors, try Roadkil's Unstoppable Copier. It's old, but might still work. Or try its alternatives.
