[rescue] Seagate ST118273LC noises?

[Patrick Giagnocavo]

Does anyone have experience with seagate drives like this and the
noises they make?  I hear a noise that reminds me of the full-height
Fujitsu drive I had 10 years ago.  

When busy, a sort of "chunk-chunk" noise with a bit of vibration you
can feel thu the chassis of the machine it is mounted in.  Format
reports no errors in the drive.  

Is it just a typical noise for these drives?
