So, your disk does not contain a valid secondary GPT header.  That 
explains the complaints about a corrupt secondary GPT partition table.


At this point, options include:

1.  Ignore it.

2.  Zero-fill the last 33 sectors of the disk.

3.  Zero-fill all the sectors after sda5.


This topic was a tangent off your OP.  Are there any remaining issues 
that you wish to discuss?
