Can I know if my disk is going bad.

[Rohit khaladkar]

Hi All,I am using Red Hat Linux 5.2 OS . I wanted to know if by any means
there is a way to find out if my disk is going bad.I looked for some command
and found out "badblocks" command for the same.But the problem is this
command takes lot of time to execute.

Please let me know if anyone is aware of any other way of finding it out, if
the disk is going bad.

Thanks!
