[SOLVED] Mobo won't detect HDD which works in other PC --- only 4 of 5 WD 3.5 HDDs work ?

[dew.shashwat]

I have 5 WD 3.5 4tb hdds. My mobo b550 detects only 4 of them. When I plug the 5th one, it doesn't show up, but the same drive works with my other PC.

PC config:
Aorus B550 Elite ax v2
Ryzen5 3600
16x2 3600mhz Ram
2x 1tb nvme
1 sata ssd
RTX 3070

pci to 4 sata x1 card

The problem is, b550 board only has 4 sata ports. All of them are connected to 4 WD 5TB drives.
Now the M.2 slots are occupied with 2 nvme drives.
I am using the pcie to sata card to connect another 2 drives.
Now whatever slot I try, be it on this expansion car or on the MOBO, only 4 out of 5 WD drives are detected. I checked, all drives work, as I am trying to move this 5th drive from my other PC to this ryzen5 PC.

The system detects: 2 nvmes, 1 sata ssd, and only 4/5 HDDS.

What could be the problem ? Expert help required.
Thank you in advance guys.

Look in the motherboard's User Guide/Manual for supported SATA configurations.

Not all SATA ports may be available depending on other installed components.

https://download.gigabyte.com/FileList/Manual/mb_manual_b550-aorus-elite-ax-v2_e.pdf

Verify that I correctly matched the User Manual.

Read the entire manual: However a quick scan found SATA information on physically numbered Pages 17 and 29.

Storage Interface information is on Page 7.

From my reading of your manual, the usage of the 2 M2 connectors should NOT result of the disabling of any SATA connector on your specific mobo.
So, you clearly have a problem: be sure that you have the latest Chipset drivers and eventually Bios.

The problem is all the 5 hdds are working.
But the sata expansion car detects only one.

My board has 4 ports, and all 4 detects 4 wd hdds, but the 5th connected on the expansion card does not show. Only the ssd connected on the expansion card shows up.

do these new sata drives have some kind of jumper, like in the good old IDE days ?

I also have the latest bios updated.

No there are no more jumper (the master-slave thing does not exist any more).
In the Bios are all the Sata connectors from the add-on card visible ?

Yes, 4 wd drives on 4 sata on-board ports are visible in bios.

No, only 1 sata connectors from the add-on card shows. which is my adata 2,5 ssd

And all SATA connectors on the card are functional ? When you test them with the visible SSD ?
And if you put this card in another PCIe slot ?

 

[dew.shashwat]

yes, all sata controllers on the board are working fine.
Recent development, I managed to detect all 5 WD drives in the bios (combined on-board + expansion card).
But as soon as I connect this adata ssd (boot drive), one one the wd drives disappear.

Result remains same irrespective on which pcie slot i connect the expansion car on.

My best guess, is that your are hitting the max number of PCIe lanes available.
If you REALLY need this huge amount of data online, maybe putting all these HDDs in a NAS would be the best solution
