Problems using a SATA drive connected via USB to My Book World Edition

I can’t seem to use copy manager to copy files from the NAS to a USB connected SATA hard drive.  I have been successful using a USB connected PATA hard drive.  I tried formatting the drive as FAT32, but that didn’t help.  Funny thing is that WD Link recognizes the SATA drive, but I can’t access it nor use copy manager.  Any advice??

Hi, what is the capacity for the SATA hard drive?
