The syntax from check_disk:

# ./check_disk -h
check_disk (nagios-plugins 1.3.0) 1.7

This plugin will check the percent of used disk space on a mounted
file system and generate an alert if percentage is above one of the
threshold values.

Usage: check_disk -w limit -c limit [-p path | -x device] [-t timeout] [-m]
[-e] [--verbose]
       check_disk (-h|--help)
       check_disk (-V|--version)

Options:
 -w, --warning=INTEGER
   Exit with WARNING status if less than INTEGER kilobytes of disk are free
 -w, --warning=PERCENT%
   Exit with WARNING status if less than PERCENT of disk space is free
 -c, --critical=INTEGER
   Exit with CRITICAL status if less than INTEGER kilobytes of disk are free
 -c, --critical=PERCENT%
   Exit with CRITCAL status if less than PERCENT of disk space is free

Did you remember the percentage '%' in your limits ?? If not, it checks
kilobytes instead of percentages..
