It is very likely the manufacturer modifies the firmware, this is common for disks intended for arrays. However, if you read the manual I send and look around at Dell support questions, some of the disks shipped by Dell apparently have out of date firmware and will be rejected unless the firmware update is applied. This is just my best guess from prior Dell experiences and from reading between the lines of Dell's site/manuals. I hope you do find someone who has tried it though!
