Don't forget that some HDD's can make a beeping like noise when they have
crashed.

It would go Beep shuffle shuffle shuffle click click click Beep. The Beep
was more a modulated corrugated iron type noise - don't listen too closely
and it sounds like a beep, listen closely and its more a fast series of
zips...

So technical!

[Hardrives slow and beeping]

And, if you examine the Hardware Monitor page in the BIOS, how
are your power supply voltages ? It could be that +5V is low,
and that is upsetting the drives. In the Asus group, we get more
power supply failures, than motherboard failures, so check that
first. ATX power supplies tend to regulate to +/- 5%, so the 5V
is only allowed to drop to 4.75V or go as high as 5.25V. If the
power supply is off by 10%, i.e. 4.5V, the disk drive controller
may have a problem with that.

If the power looks good, then go back to blaming the motherboard.
RMA if there is any warranty left.

The voltages are a bit out, but the 5V seems fine:

12V 12.128
5V 4.977
3.3V 3.072
VCore 1.825 (the BIOS is trying to get 1.75V here)

Could the 3.3V be at fault?

The hard drive is powered by +12V and +5V, so +3.3V doesn't
affect it directly. But the 3.3V does power a lot of chips,
and it could be indirectly affecting things. If you own a
voltmeter, it wouldn't hurt to grab the 6 pin AUX connector,
if your power supply has one, because it has a 3.3V pin on
it, and you could measure the voltage on that pin. Connect the
ground of the voltmeter to a lug on an I/O connector
on the back of the computer, to avoid the chances of
shorting the meter probes together (big sparks).

If you don't own a voltmeter, then it is a tough call to
make, whether to invest in another power supply or not.
If you have another power supply lying around, try swapping
it, and see if the +3.3V improves.
