Bad blocks - UncorrectableError

[Larry Cook]

I'm looking for some guidance.  Below are some of the entries from my 
/var/log/messages.  I'm running RH8.

Should I just run e2fsck with the -c option so it will map the bad blocks that 
it finds?  If so, what's the proper way to fsck the root filesystem since it's 
mounted?

Or should I use the diagnostic boot floppy that came with the Western Digital 
drive to do the mapping within the drive?

Also, is there an easy way to determine what files are affected?

You'll notice that the sectors are all consecutive multiples of eight.  Is 
that expected due to interleaving or something, and thus indicates that one 
physical area of the disk is bad, or do I have multiple bad spots?

Thanks,
Larry
