Ok, this is starting to make more sense. I ran the "-t offline" again, and 
then a short offline test, and looking at the following again:

197 Current_Pending_Sector  0x0012   100   100   000    Old_age   Always       
-       1
198 Offline_Uncorrectable   0x0010   100   100   000    Old_age   Offline      
-       1

I believe the "1" RAW_VALUE is what you mean by the hard drive not zeroing it 
out.

I've modified to the following in my /etc/smartd.conf:

/dev/hda -a -C 0 -U 0 -o on -S on -s (S/../.././02|L/../../6/03) -m 
root@localhost.localdomain

Which I believe should resolve the unwarranted warnings.

Many thanks for your help.

Michael.
