As hard disk manufacturers -like all PC part manufacturers- cannot test a HDD as a stand-alone device, they are tested in a representative configuration, and will comply as such. That is not your configuration. You have no guarantee that the final HDD will be below limits in your configuration. It may have been tested with a 5 cm SATA cable and in high performance enclosure.
The only benefit to customers of a certified HD is that it IS possible to apply them below limits. I would suggest your customer to carry out RE test on any future configuration in their own representative configuration. If that test will give enough safety margin, than that could be used as a test report reference.

When having a computer system EMC tested, and different hard disk options are expected to be used over time, but the exact details (e.g. part number) of those hard disks is not yet known other than the requirement that they be certified on their own to relevant EMC standards, is there a standard phrase that is used in the test report to describe the situation (such as "... including any hard disk certified EN XXXX for immunity and EN YYYY for emissions")?
