A drive can die at any time, even from another cause not
related to a beeping sound, so the safest answer is to back
up your data now and consider how valuable it is that the
system be as reliable as possible. If that highest
reliability level is really important then replace the
drive, and if not, keep using it after making a backup of
the data.

9 months of power-on hours isn't very long, the drive ought
to have a few more years of life at this period of use but
again a drive can fail at any time and the older it gets
past a couple years old, the more likely. Well actually
infant mortality is also bad for hard drives but it is past
this age.

I wish I could predict if it's going to fail some month soon
but there's no way to know unless you see smart values
changing significantly, which you could choose to monitor if
there is software available for your OS. I don't know which
Smart monitoring utility is the best but Google searches
will find a few.
