Question Trying to add 3rd Hard Drive to Z420

[Thedeathadder]

Trying to add a 3rd SSD drive to a computer used for media projects. I read I can add 4 drives to the Z420

I Installed 2 SSDs in Sata 6Gb/s

Cant get additional SSD as well a DVD-RW to work in Sata 3Gb/s

I read I could get up to 4 SSDs/HDDs into the Z420, read you could get a DVD-RW working in a Sata 3Gb/s

Is this true or false? Should I try reconnecting the plugs?

Everything works when I plug them into the 1st two black Sata 6Gb/s ports , nothing in the remaining 4 white Sata 3Gb/s ports

Am I missing a driver or something? Currently using search engines on multiple websites right now for the answer while also popping the Z420 open constantly to try new ideas, this post was not my 1st step

Any ideas or am I out of luck with those Sata 3Gb/s?

Are there any M.2 SATA or NVME slots on board?

If so, often SATA ports can be disabled in the BIOS to accommodate this, so, look for BIOS options that might affect this)

Haven't pulled open the machine today to check for the slots, I will right now...but went into the Bios and everything appears fine, all six Sata slots 0-5 should they are available and enabled

Do you think I need to use the jumper of the z420 motherboard to reset and get the Sata 2-5 working again like the sata 0 &1?
