My WD15EADS (Western Digital 1.5 TB 32MB Cache) is having some serious problem, it turns a few times then gives up. Neither Win 7 or Vista can read the drive. Vista sometimes displays WD , that's all.
Sounds like a eminent HDD failure.Anything made by humans is by nature prone to failure at some point(that includes computers).
There are some recovery tools out there, check other HDD problem posts to get the suggested s\w that MIGHT help.Otherwise,need a good doorstop?
