[SOLVED] Help with sata connections on Dell T7500

[ozrock]

I have 2 drives connected via the blue cable were there when I bought it and I added another drive to the left of the blue and it has been fine for months.

It shows on the image.

Now I want to add another drive and I tried that red cable on the right side of the bank to the blue mobo connector and the drive also did not show.

I have also tried to connect the new drive to a bank of connectors on the left side of that power connector, but it does not work there either.
The drive itself is new does work on other boxes.

What am I doing wrong and do I need to change anything the bios?

A bit of a Dell newby to make things worse

I see the connectors here but do I need to change anything in the Bios to make them work?

Strange. These are usually just plug and play.

Here's what I would do to diagnose. Remove the working red cable from that drive and attach it to the new one. If the new drive shows up then the drive is okay.

Next, remove that red cable from the port it is in and plug it into the port that you want to use. If the drive shows up there, then you were trying to use a 'bad' cable (which may not actually be bad per se, but just doesn't like that drive/port combination).

Many thanks for the help guys. Strange as the images show up on my post.

I uploaded them to one of my sites and gave the link. Anyway I have done the imgur thing here now too.

I saw your images (and still do), so that's how I knew what you were talking about with the wire colors.

Funny that !

I thought if you didn't see them like rgd1101 didn't, you might be psychic or have these boards imprinted in your brain 😀

I will give your suggestions go when I get a chance to get off the box.

I'll post the results.

Thanks again

Haha, if I was a mindreader I would be posting answers before questions are posted, lol!

Definitely try it out and see what happens. I've seen certain cable/port/drive combos not work or have issues before so my hunch is that is what it is.

Well!

Plugged the new drive into the working red cable and it also worked via sas plugs on inside of power plug.

Took that working cable to the corner 3 sata plugs and it didn't work with the original drive or the new drive .

Used 2 different red cables.

So it seems that those 3 sata plugs on the corner either do not work because there is something wrong with them or they are not turned on in bios.

I am lost in the Dell bios so would need help enabling them in there if that is what is needed.

So.... h..e..l..p.. !!

Okay, so it looks like you have a built-in sas controller as well as sata on the motherboard. But it seems like the sata controller is disabled in the bios and that's why the other ports aren't working. Go into the bios and enable it and the other ports should work:

Ah Haaa. Yes you're right.

Enabled Sata 1 and 2 and it is fine, at least in the port I used.

Many thanks..

Stay safe

Sata 1 and 2 B4 enabling
