Yes it should. Even if you are not writing data you will get noise for at
least two reasons.

1) syslog writes 'Mark' records every so often which will eventually be
flushed to disk

2) Most drives shuffle the heads aroun and reread data occasionally just
to keep the head in the right place and everything happy.
