That's actually a fairly well-known false positive.

If you want to silence that message, search your /etc/rkhunter.conf file
for the part which has RTKT_FILE_WHITELIST= in it, and then whitelist
that particular file.  My own rkhunter.conf file has this in it:

RTKT_FILE_WHITELIST="/etc/init.d/hdparm /etc/init.d/.depend.boot"

That string typically shows up in those two files, so adding them to the
whitelist gets rid of the message.  It's a known problem with the
rkhunter db.

Search Google for "rkhunter hdparm" and you'll find all kinds of
references to it.
