When you erased the drive was it with the GUID partition tablenor MBR? Try with the former and the volume in the Mac OS Extended (journaled) format.
If after that you still can't back up then it'll most likely be a hardware issue Regards Sam MacAmbulance Ltd.

I followed advice on Seagate website and erased the disk in Disk Utility. I’ve reformatted it as Mac OS Extended (Journaled) and I’ve also downloaded and installed Paragon NTFS for Mac OSX, which the Seagate site says should sort the problem. Except it doesn’t. Is there anything else that I could try? (Otherwise I’ll be returning to Amazon). Thank you in advance.
