My 320L successfully back-ups up to an external hard drive connected via the USB port on the back. However, when I attached the Hard Drive to a computer to "view" the files on the hard drive, my computer said the hard drive was unreadable/corrupted. However, when I attach the USB hard drive to the NAS, I can access the USB Hard drive backed up files via Network Sharing (it shows as a shared hard drive on the NAS).
Any ideas why I can't "normally" read the files on the hard drive?
