Buffalo Linkstation Pro LS-V3.0TL occaisonal click noise?

[pwjone1]

Pretty much brand new Linkstation Pro LS-V3.0TL, installed and seems to be working fine, copied some data over, no complaints, and the unit is relatively silent once booted, but I am noticing an occaisonal clicking noise, just every so often.  Comes in a sequence of 2-3 really quickly, then no noise at all.  It can quite some time between these noises, so I was kind of guessing it might be the heads unloading or some sort of spin down to save power, but I figured I'd ask if it's normal.  Seems to happen sometimes when the unit is not in use, and just every so often, haven't had it running long enough to know much more than that.  Is this normal behavior?

I should have mentioned, I did reflash to the latest firmware, 1.62, seems to have not made much difference.  The unit had arrived with 1.60 level.

Still clicking every so often.  I'm going to feel silly calling Buffalo to ask about it.  Anyone know what it might be?  Sounds sound like a hard-disk reseek, kind of louder than that.

enable email notification and it will show if there are any bad sectors on the HDD. The noise might just be one of the HDD arms resetting.
