Hi Ashleigh,
Well the news gets better!! (In my opinion anyway)
I have 3 Seagate™ Hard Disc Drives that do exactly the same as yours...it is an inherit idiocyncrasy with them, and nothing at all to be overly concerned about.
Seagate™ themselves have told me that it is quite normal, for them to 'grate' whilst "spinning up", and nothing to be concerned about.
So there you are...problem solved. (hopefully) :Laugh:
Kind Regards,
