Howdy,

I finally got a new 3TB hard drive.  I got one on sale for under $100.
Anyway, I put it in, did the LVM thing and set up my backup script, very
basic as it is.  A little bit ago, I noticed a sound.  It's not a click
or a metallic type sound.  It sounds like the heads are doing random
reads/writes and the heads are moving but doing so noisily.  Thing is,
there is no drive activity according to gkrellm or iotop.  All the
drives should be basically idle.  I even went to single user mode to be
sure nothing in KDE was doing some index thingy or something.  Still,
nothing showed that there should be any drive activity, including the
hard drive light on the case.

Also, I do not know WHICH drive is making this noise yet.  I have four
in there running and they are physically mounted close together.  I'm
not sure I would know which one it is even if I take the side off the
case.  I just know that it is making this odd noise.  Here is some info
from hdparm:

That's the new drive up above.  Old drive that is basically the same
drive, different batch I would assume, is below.


root@fireball / # hdparm -i /dev/sdc

/dev/sdc:

 Model=ST3000DM001-1CH166, FwRev=CC29, SerialNo=W1F4C31Q

The last SMART test I ran showed no problems but I have a fresh one
running as I type on all drives.  Will update if it shows anything.

Thoughts?
