Please correct me, if I am wrong. As far as I know, bad sectors are blanked 
out by the hardware itself. If bad sectors are detected, the software tries to 
read and then move the data to a good sectpor and after it sets the sector as 
dead. So this sector does not appear again. 

Maybe this is the reason, why e2fsck only sees and shows good sectors, just 
because it never checks sectors already marked as bad by the hardware itself.

However, I maybe wrong. You should watch this, if more errors appear, think of 
exchanging the drive before it is brain dead.

Best

Hans
