They're not, they're typically made of machined aluminum; in fact the  
technology used to make hard drive cases lead to the technology used  
to make MacBook Air and now the MacBook cases, all start with a solid  
block of aluminum.

Typically the only ferrous parts of a hard drive are the brackets the  
magnets are attached to.
