Ok, so over the weekend I decided to buy a 500GB usb powered hard drive. Loaded all my songs on it and got the unsupported error. Then remembered it had to be formated to FAT32. Reformated and reloaded all my songs, then got the No Songs error. After a few trial and error I figured there must be a space limitation. so I recreated the primary volume to 150GB and reformatted as FAT, no problems. Then I resized the volume and reformatted again till I got the no songs error. Currently I have it set to 260GB. It gave the no songs error at 270GB. I have about 120GB worth of songs on the hard drive and it takes 45sec to a min until the device starts playing. So I've partitioned the rest of the drive as NTFS for files and such.
