I am sure you have heard about this lady’s sailing expedition.

 > Early this morning, one of the Sony VAIO laptops that power
 > the critical information systems onboard B&Q - including
 > routing and navigation software - suffered a meltdown. The
 > VAIO's have survived 70 days without a glitch, despite continual
 > pounding onboard B&Q but last night's storm was the last straw
 > for one of the two hard disks. At 0750 Charles Darbyshire,
 > Technology Manager, received a call to report the failure and
 > just seven minutes later, MacArthur had replaced the hard disk
 > with a pre-start mirrored backup unit, re-configured the software,
 > and was up and running again - preparation counts!
