That's interesting, to say the least. I thought they stopped doing that quite a while ago now that UEFI is becoming the norm?
I used to manage a wide deployment of Dell workstations across multiple locations in a small hospital district. We had a Windows 7 image that we'd deploy (nuking all the partitions in the process, including any Dell recovery partitions), yet diagnostics would continue to be available for those times when we encountered hardware issues and needed to send machines back to Dell (and I'm pretty confident that we didn't preserve any diagnostic partition(s) during the imaging process).
I suppose older machines probably required a diagnostic partition, in which case I stand corrected.
