That´s an other matter. After hiding the manufacturing defects with 
low level formatting no new bad blocks should appear. It´s normal 
to use a hard drive for years without getting a single new bad block. 
When you get some, it may be an isolated case or it may be the start of 
the deteriation of the drive. Because of this, when you find bad blocks, 
it´s wise to regularly test your drive for example with the 
manufacturer´s test program.
