Im a little concerned that up til now my dead quiet HDD has become inconsistently rattly.
It kind of sounds like an old hard disk when you could hear the thing spinning but when matching this to the HDD LED it is not always syncronized.
Can I assume therefore that as it has always been quiet, for over three years, the barings may be wearing?
I have two HDDs the second one (2 months old) contains some digital video files and my C:\ image files so I am sure that it is my main HDD.
Another thing, I have always heard the drive coming on from a suspend mode when using the computer whilst just browsing the net to actually doing something HDD intensive, sounds like a faint motor spinning but since the above mentioned rattle this has gone away.
