It's a Seagate, isn't it? I am seeing new ones do that and affect the overall system performance. For now the fix is to get any other make.
If you are not having performance issues you can ignore it but don't trust it.
HEAT? The second link says the drive is out at 65C where as the maker only specs it up to 58C. May be why the 01 and 07 values took off?
