Meanwhile, I have fixed the first problem with the output - the reson 
was the permissions of the folder. Nagios was not allowed to read this 
folder. Adding nagios to the right group, the output for /dev/hdc3 is OK 
now - Thanks a lot for your help...

Thanks - the workaround is OK and works fine!
