Hello Jelliebean71,   A Dell certified drive would have Dell on the label.  The drive you listed does not appear to be a validated hard drive so we could not confirm if they should work.   I'm listing a few 10TB Dell drives you may consider. If you contact Sales you may see if they have others available.  There are third party companies that can also offer Dell drives some examples:    _www.impactcomputers.com   _www.serversupply.com (not affiliated with Dell)   When you contact Dell to purchase one of these part number, please ask for the Spare Parts Sales department.

PowerEdge R720xd.  I am having trouble getting this server to recognize the front twelve HDD slots.  I have three installed and they are seated properly, but it will not recognize them at all in the PERC controller.  I have checked that they are compatible and I have tried different slots.  I have used an OEM PERC controller and one flashed to IT mode and they both recognize the rear two HDDs but not the front twelve.  Any ideas?  I’m just barely above a novice at this so any help is appreciated.
