Additional Hard Drive Info?

I have a requirement to add a tracking ID and physical location (single-line text field) to each of our hard drives. The tracking ID is generated by another system and must (somehow) be associated with a specific hard drive. We are currently running weekly Domain scans which return basic information on the workstations, including (some) hard drive info.

Is there a way to add this information to each hard drive in SDP? It's important that the tracking ID and physical location be associated with the hard drive, not the workstation. If it is possible to do this, how would I go about implementing it? The follow-on question will be how to generate a report of the hard drives?

We're using SDP v9038 with SQL Server 08 R2.

Thanks in advance.
