Hello I just bought the Pioneer N-50 a couple days ago and I can get it to read usb sticks, but not usb hard drives. I see in the manual that it can't read usb hard drives but on forums online people are saying it works, so I wonder what is wrong. I converted the hard drives to FAT32 from NTFS. They are old hard drives, more than 5 years old, with their own power supply which I plug in. Anyone experiencing this? It seems a bit strange that a simple hard drive can't be read.
