Indeed, it is.  ;)

sevenlayermuddle:
Any magnetic disk is easily hacked by the simple expedient of dismantling it down to individual platters, then spinning up the platters in a clean room with an appropriate rig and head readers.   The HDD PCB electronics are pretty much irrelevant, as long as the magnetic surface is largely intact.

That is why when disposing of an old HDD, in addition to zero-filling, I usually physically trash the platters - a few 3" nails driven through can be convincing, and would frustrate most/all hacking Attempts. 

It is also why (or at least one reason) I am wary of SSD drives.   There are no platters to trash, and so nothing to convince me the stale data won't be hacked. ???

A bonfire, blow-torch or a furnace would probably be sufficient.

I have a 1000 degree Morsų stove which does a decent job.
