I have a Thinkpad 600E with 10G drive and no strange sounds at all from it.

In the past I have seen desktop systems with hard drives from what used to be
Conner have problems under Linux but not under Windows, such problems
inevitably resulted in loss of data (but no strange sounds AFAIK).

I have a single pixel on my Thinkpad screen which is always at half-brighness
on the red scale.  If I have a typical desktop with white background or grey
title bars in the area then it's not noticable.  In text mode it stands out
from the black background.
My company laptop is a Compaq which has the same problem (but the pixel is
white).  The problem is that making the 1M transistors in a TFT without any
errors is almost impossible.  Apparently IBM won't give you a warrantee
replacement on the screen unless at least 20 pixels have problems.  This is
understandable as the TFT screen comprises half the cost of the unit.  If
they made the warrantee level 5 pixels then they would probably have to add
25% to the cost of the Thinkpad to cover all the screens they would throw out
at the factory...

I suggest recording the sound and asking IBM for a replacement hard drive.
