It could have been a problem with the redundancy rather than 
the disk
itself. I recall reliability problems with raid systems when 
they first
emerged. From the description, it is more likely to be a 
software problem,
as if it was hardware, it would be a simple matter of 
replacing the particular
disk, assuming there was redundancy.

Also, I wonder what the contracted outage window was.

The timing is most unfortunate. Football Grand Finals, 
University and NSW School Holidays.
