Aida32 program question

Hope this makes sense. :-)

I have 2 harddrives. 40 GB Seagate , this one came with my PC no
installation CD. I also have a 120 GB Western Digital.

I have a retail version of WINDOWS XP and the Seagate didn't come with a CD,
so I used the licensed version and put in the Product Key for the OEM
version. Now on the Aida32 program it shows that the version is retail and
it gives the Product ID as an OEM?? . I purchased the retail for my 120 GB
Western Digital. Is there somewhere I check in the system files (Registry)
for this information?

Thanks bunches, Donna J.
