error when connecting a USB device

Is that drive USB powered? If so, that's a pretty big drive to expect a NAS to power on its own (though USB3 is suposed to be rated at high enough current for most). If the electronics is powering up but the drive isn't spinning up, that could cause it.
NOTE: If a drive comes with one of those cables that lets you plug into two USB ports to get enough current, it's not usually going to work on a ReadyNAS.

Does the drive have multiple partitions? (Windows Disk Manager will show you).
No, the device is 1 large partition.
Hi papaj0hn,
Is it the same issue when connecting the storage device on any of the USB ports of the NAS (one USB2.0 port on the front panel and two USB3.0 ports on the rear panel)?
Also, just to confirm with reference to Windows Disk Manager, does it also show only one partition when running list part in diskpart via cmd?

Because of no solution, I plugged the device into a windows desktop & used robocopy commands to copy the data. Yes, Windows device manager and diskpart both show 1 partition. I do have another 14TB (Western Digital) USB plugged in in the back of the NAS and it is recognized and working properly for my back ups. By this 5TB Seagate is not recognized. When plugged into the front USB port, I get no recognition at all, with the top back USB port I get the same warning as before even though now it has the data from the robocopy. Again the warning is "External storage device is connected but the file system is not recognized."
Can you format the disk as EXT3 or 4 from the NAS when plugged into the USB3 port?
ETA: What is the exact model number of this drive?
