Losing data with routine cp and mv -- "cannot create hard link"

- Subject: Losing data with routine cp and mv -- "cannot create hard link"
I use Cygwin 1.3.17, NTFS file systems, and Win2000 (see
excerpt from cygcheck -s below). Both with cp and mv, I am
getting error messages when copying or moving rather large
directories (1.4 GB, 89,000 files). For example, the command:
$ cp -Rip p:/rchive q:/
starts off fine, but half-way through the job, error messages such
as the following start to appear:
cp: will not create hard link `q:/rchive/foo/bar' to directory `q:/rchive/fli/bers.gif'
..where the both filename A is always a directory name
and filename B (called a "directory" in the error message)
is usually a file, not a directory.
While showing these messages, cp and mv continue to execute
normally -- with error messages appearing intermittently --
except the directories named by filenames A are not copied,
i.e. the data is lost. (Good thing I was paying attention
and not running these in batch mode!)
I could not find anything relevant in the mailing list archive
or FAQ. Can anyone advise? Is this an inherent limit of
these commands? Should I perhaps be using xargs?
