Check out certain logs like btmp (the output you get when you use the command 'lastb').<br>
Hacking attempts can swell it large, a publically availbale IP can attract 2GB of hacking attempts a year.<br>

Some distros do not have a well configured default logrotate.conf (Centos 5 for example), your conf may need something like this added:<br>

You don't run 'rsnapshot' do you? Because that’s notorious for eating up<br>
empty space on the hard drive!<br>

The link talks about ext3 - the drive is ext4, those that make a<br>

Also I was to run the tune2fs -c 0 -i 1m /dev/hdXY command is<br>
