Tar recreated the hard links to the files in the same directory upon
extraction.

I think you will have to elaborate on this 'different filenames with
same case' thing because that is not supported under Windows, which is
likely your actual problem, not tar.  Windows file systems preserve case
but are not case sensitive, so you cannot have two files with the same
filename but different cases.  That is a design limitation and there's
nothing tar can do to get around it.  You can however try a managed
mount.
