I can thank WD...
...for the most important computing lesson of my life.
Bought a MyBook 1TB to replace a number of HDDs floating around the place, and spent about a week moving all photos & videos from various laptops, an old desktop and a couple of external drives onto the MyBook. Then deleted them all off the various devices so we had one, easily manageable photo and video library.
Then went on holiday for a week.
Then came back, turned on the MyBook and it refused to start up. Head crash.
Drive was a week old, lost all data. WD offered to replace the drive but wouldn't pay for data recovery (ON A WEEK OLD DRIVE). I didn't have the 1200 quid recovery would have cost, so had to explain to the wife that we'd lost everything.
I decided on a point of principle to smash the drive into component atoms with an 8-pound hammer, then put the bits in a box and drop it off at WD head office in Leatherhead with a spicy letter attached. Enjoyed doing that immensely. Didn't get a response though.
