well now I really need advice, the data centre guy successfully inserted another 
disk in the right place and it appears to be the same model. However, smartctl 
-a /dev/ad4 seems to show a number of errors and many of the indicators are 
prefail or old_age.

In addition the disk doesn't have exactly the same length so when I tried to 
insert gmirror complains that it is too small.

What are my options?
