Media player not recognising hard drive

[Fortcon]

Hey guys, just recently bought a media player & am having some troubles. I've got two portable hard drives (250gb & 500gb) & neither of them seem to be recognised by the media player. They both have a y-cable usb & the media player has 2 usb outlets, but it still doesn't recognise either hard drive.

Is there anything that anyone can think of, that might be the problem?

thanks

What's the make and model of the Media Player?
