I have had a large quantity of the Caviar Blue 500 Gb drives fail is the last few weeks. Many are from Acer systems but not all.
They include the WD5000AAJS and WD5000AAKS.
They sound like they are resetting and then the motor slows down and it resets. The process starts again.
What is killing these drives?
What part is failing?
Can you swap main boards with a good one to recover data?
Should I replace all of these drives now, before they fail?
Are new WD drive suffering the same problems?
