Here in the US at least, most companies that provide confidential
document shredding will take magnetic media to be destroyed as well.
Does your company use such a service?

This could get rid of it and your boss too.

save up a pile of junk and then rent one for a day.

If it's polyethylene of some sort, then it's practically indestructible! Well,
almost.
Looked up 'polyethylene' in wikipeadia; here's what it says:
"Polyethylene (other than cross-linked polyethylene) usually can be dissolved at
elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in
chlorinated solvents such as trichloroethane or trichlorobenzene."
Mmm, what yummy cancer-causing chemicals!
BTW, it also says that 60 million tons of polyethylene are produced each
year--so all of it will probabably still be around in landfills long after the
human race has died out!
