Bad sectors on harddisk (question)

[William Park]

What is conventional wisdom when you encounter bad sectors on harddisk?

I am only aware of 
    umount /dev/hdb1
    e2fsck -c /dev/hdb1		(read-only check)
or
    umount /dev/hdb1
    badblocks -n -b 4096 -o xxx /dev/hdb1	(non-destructive read-write)
    e2fsck -c -l xxx /dev/hdb1

Is there better way of 
    - identifying bad sectors (/var/log/syslog says so).
    - then mapping them out, so that filesystem does not use them.
?
