From a Failed Hard Drive - Changing the Logic
One possible cause of hard drive failure is
a problem with the logic board (the electronics
unit) onboard the hard drive. If the logic board
fails your computer will not be able to access
the data on the hard drive. To recover data
in this case you will need to change the logic
board. You must replace the logic board with
one from an indentical hard drive otherwise
it will not work. Once the logic board is replaced
you will know right away if it was the problem
since you will be able to access your data again
as soon as you start the computer.
