I get the feeling that my hard disk is very slow. Is there a way I can verify and tune it?

Mon, 07 Aug 2006 18:46:07 +0200

You can use hdparm to tune your hard disk. On Debian, you would run

apt-get install hdparm

to install it.

hdparm --help

shows a list of all available options. To get more information about your hard disk, run

hdparm -i /dev/hda

tar xvfz chkrootkit.tar.gz
cd chkrootkit-<version>/

Afterwards, you can move the chkrootkit directory somewhere else, e.g. /usr/local/chkrootkit:
