I'm surprised. Did you run XXCOPY from the NT4 machine (the E: drive is a local drive on the NT4 machine) or on another machine? (What service pack does the NT4 machine have? Mine has SP6.)

I just tried, on the NT4 box,
md c:\xxc
xxcopy c:\some_dir\ c:\xxc\some_dir\ /t /tcc
and it built the directory tree (15 dirs at 3 levels) for that piece of the drive; then
dir c:\xxc\some_dir\ /tc /s | find ""
showed only directories with 2002 timestamps -- the "create timestamp" for each directory was created correctly, as expected. (I do note that the directory c:\xxc\some_dir has "now" as the timestamp, but if I had used
xxcopy c:\ c:\xxc\ /t /tcc
I feel confident that some_dir would have had its timestamp set to match. I just didn't want to build so much of a directory tree for no reason.)

Then I did
xxcopy c:\some_dir\ c:\xxc\some_dir\ /clone
and it copied all the files, after which the same "dir" command showed that the create timestamps of those directories had not changed.

When I repeated from another machine running Win2K, using
\\p300\boot\
instead of c:\, and using \xxc2\ as the target, the directories (except the "top" one) all had the right timestamp.

Kan, do you have an explanation for why things would be different for us?
