Disk scan utility?

[DARREN BROWN]

When I run e3fsck -cf /dev/hda3, I get a message stating; WARNINGS!!! 
Running e2fsck on a mounted filesystem may cause SERVERE filesystem damage.  
Found out that the -cf does a badblock test for you.  Cool....

Has anyone ran this type of command line, got the message, and went forward 
w/ the process it runs?  What happened if you did?


Regards,
Darren
