Hi. I have an hp z820 workstation. When i connect my hdd and ssd to top 2 ports/hdd bays they are detected and work but as i connect to the other ports bottom ones the disks are not detected, not even in BIOS. Help appreciated.

as i said the white ports next to the 2 blue intel std SATA ports are called the intel "SCU" ports and the correct intel RSTe (enterprise) driver must be installed installing normal RST (non enterprise) drivers will not work as they have no support for the intel c600/602 chipsets "SCU" sata ports v4.6 is the last to support c6xx chipset and is win 7-10 certified

the z820 has three different Hard drive controllers
the 2 blue ones are standard intel 6GBps ports, no drives needed, all os's will include the necessary driver
the 5 white ports next to the blue ports are Intel "SCU" SATA ports and require the Intel RSTe (enterprise) driver v4.3/4.6
however once win 10 is installed, it has builtin drivers for these ports, you only need a "F6 type driver during the initial os install. due to this i recommend you connect the optical and boot drive to the sata 6GBps ports and install the OS after install if win 7/8 download the SCU/LSI drivers
the 7 white SAS/SATA ports are connected to the motherboards onboard LSI 2308 "mustang" ROC chip
and these ports are controlled from within the z820 bios by pressing ctrl-c when prompted
again win 10 has native support for this

Thankyou for your response dear. Yes I have windows 10 pro installed. i also checked if my hdd was showing in the BIOS or in disk management. but it wasnt showing. i tried to put it in the top 2 slots and it worked perfectly fine. i even installed the intel RSTe f6 type driver but it is still not showing in the bottom 2 bays. maybe my driver was wrong.

1. are your drives SAS or SATA
2. if SATA then move the 4 hotswap bay connectors from the LSI ports to the "SCU" ports
currently they are connected/controlled by the onboard LSI bios
as a quick test, look at the left side of the drive slots, note they are numbered, match the number with the tag numbers on the 4 cables and then move the 0/1 cables to ports 3/4 on the motherboard in other words move working drives to different ports this will test if the issue is the cable if the drives work on different ports swap drive carriers

Thanks dear. This drive that im trying to connect is a sata drive only for backup. And yes that is a Brilliant idea. I will do as you suggested and respond. I think we will be able to find the real issue. You are right it could be the cable because my other 2 drives (one ssd and the other hdd) also dont work on the bottom ports and this old drive works fine on the top 2 ports. Let me check and get back to you. Thanks so much for your guidance. Much appreciated.

Dear i plugged the bay 1 cable into port 3 instead of port 2 (port 1 and 2 are blue rest are white) and the hdd that was previously detected in port 2 stopped showing in port 3. It means the cable is good. The white ports arent working. Cable is not the issue. Does this mean my drivers are missing?
