Without some sort of PC to access that HDD it is useless. In order to do anything with the HDD you need an operating system that can access NTFS or FAT32 formatted partitions as well as decode the audio file to play the data as music. I don't think there is a device that can do this with an external HDD other than a PC but maybe someone will enlighten us both. You may be able to get a Home Theatre Media Center and transfer the files to it, or better yet even hook the external hard drive directly to it but I'm not sure, as I have no experience with Media Centers.
