By "disk is broken down" do you mean if the hard disk is failing or is
powered down? If you want to see if the disk is failing, on GNU/Linux,
the SMART monitoring tools package can help. On a Debian system, you can
install it this way:

apt-get install smartmontools

and try looking at the the smartctl(8) man page.
