    It is probably using NTFS as file system, to check:
    Finder > select external HDD >> GET INFO >>> Format and Sharing & Permissions

    PS: Time Machine does not work with NTFS formatted HDDs, maybe you can partition it though, but as I don't do it that often (using Windows and external HDDs formatted with NTFS), I don't know about that particular problem.
    Maybe have a look at Advanced Search to find similar threads:

    No need to get a special HDD, as every HDD can be formatted with every available file system. You just need to format it correctly, but as your HDD already is formatted via Windows, you would lose all data during another format, thus you could partition it, but as I never had to partition an NTFS formatted HDD for Time Machine use, I don't know the steps. Maybe the Advanced Search I pointed to or the following FAQ can help.
