Based on my DOD experience, a magentic field strong enough to wipe the data destroys the drive motor as well. There's also (if you get deep enough into the forensic technology field) an ability to get data off disks that have had the DOD approved 7 write overs. So while the 7 times overwrite was approved for disks with secret info, disks with higher level info (e.g., Top Secret, Special Compartmented Intelligence (SCI), and even higher) had to be shredded. Not mashed but actually shredded into tiny tiny pieces)
So it all depends on the level of sensitivity. Drilling a hole through the disk will prevent someone from sticking the disk into another machine and reading it but most of the data can be recovered if someone wants to spend the time and money.
