Were I a betting man, I'd guess that if you left one sit on top of the drive for a couple weeks, it would be sufficiently hosed.
It's already unreadable by dint of whatever other aspect of the drive has failed and somehow I doubt that anyone at WD is going to break out the bunny suit and electron microscope to take a hard look at Lunar's data for anything short of national security or kiddie porn in between sorting out the 160 OTHER dump trucks full of bad drives they get every day. I guess it could get magically fixed and shipped off to some data recovery expert just itching to try his favorite software on a random refurbished drive, but the likelihood of that seems pretty damned small to me.
