I had a 4 year deal with WD, and my only complaint is that nothing much
broke/went wrong in those 4 years...
I had 2 minor things needing repair, and they covered it in a heartbeat,
which may or may not have been a result of no claims during my coverage.
I paid a couple Gs, way back then before aftermkt warranties increased
their rates; I was satisfied with them, but was surprised that they "let
me go" so easily at "renewal time". WD does receive generally good reviews
on this Board, fwiw.
I am flying on my own dime, going into year 9+ on my ol' X...
