As discussed yesterday, I ran this through multiple passes last night, all 
night using the non-destructive read/write tests, and waking up this morning 
to see the results all tests passed successfully. No errors were detected on 
the drive.

Booting the machine this morning, the same SMART errors were reported to me 
via email.

Yeah I'm not sure what the issue is, but appreciate your help and advice so 
far. I've learnt a bit during this process :)
