I have purchased a new hard drive with 3 terrabyte from Intenso (Memory Box 3 TB). The Philips HTS4282 2.1 does not recognize the hard drive. Although the hard disk is downgradeable. Why is that?

Please help, because I need to store my media files on the new hard drive (old one is damaged), it wants but can also play on the hts.

Thank you very much!
