Officially, those are 'comment' lines, i.e. those lines are ignored by
the program reading the config file. They're used to describe or explain
something to the person using the file. (you). 

Rant follows:

Linux programmers seem to delight using these comment-characters (#) to
'disable' certain commands, so they become like examples. It even
enriched the English language with the verbs 'to uncomment' and 'to
comment out'. 

Very often when configuring stuff in Linux, it involves opening a config
file that already includes loads of settings, but some, most, or all of
them have been 'commented out' using #-characters.  You can then select
the settings you need by removing the # character using a text editor. 

All of this is the result of lazyness on the part of the developer(s)
who didn't bother to program a basic screen or wizard to configure
things. Furthermore, they even convinced themselves that config files
are a Good Thing!   As yet, they haven't convince me though.

End of rant. :)  (Yes, there's more useful stuff to follow, bear with
me)

As it happens I played around with hdparm yesterday, because of a pretty
good article I was reading on optimizing performance in Linux.  

The article was this one, enjoy:

Note that for Ubuntu the config file is not the same as in the article
above, but from your post it seems you already found
the /etc/hdparm.conf file.
