 *  check_ide-smart v.1 - hacked version of ide-smart for Nagios
 *  Copyright (C) 2000 Robert Dale <rdale@digital-mission.com>
 *
 *  Nagios - http://www.nagios.org
 *
 *  Notes:
 *	   ide-smart has the same functionality as before. Some return
 *	   values were changed, otherwise the --nagios option was added.
 *
 *	   Run with:  check_ide-smart --nagios [-d] <DRIVE>
 *	   Where DRIVE is an IDE drive, ie. /dev/hda, /dev/hdb, /dev/hdc
 *
 *	     - Returns 0 on no errors
 *	     - Returns 1 on advisories
 *	     - Returns 2 on prefailure
 *	     - Returns -1 not too often
