[SOLVED] Unseen HDDs in New Build

[3vangelica]

Hi, I just built a new system:

PSU - Corsair TX850
M/B - ASUS ROG STRIX B450-F Gaming
CPU - AMD Ryzen 7 2700X
H/S - AMD Wraith Prism
RAM - Corsair Vengeance LPX 3200MHz
SSD - Samsung 850 Evo 500Gb
HDD - 3x Western Digital Blue 1TB
GPU - AMD Radeon RX480
O/S - MS Windows 10 Pro

The system works fine but, only the SSD and one of the HDDs can be seen. The other 2 HDDs are not visible. Not even in the BIOS.
I've tried unplugging, re-plugging, and even swapping them out for new ones but nothing works.

Any ideas from here would be appreciated. I'm at a loss.

Thanks.

Open disk management and tell us if the HDDs are visible there.

Do all the HDDs spin up? If not, could this be your problem?

I would measure the voltages at the SATA power connector, just to be sure.

New drives have a "Power Disable" feature:

One other unlikely possibility could be that your drives are configured to Power Up In Standby (PUIS), but they should still be detected by the BIOS.

Check in the Bios to make sure the Sata ports are enabled and that they are in AHCI mode (in the Sata Config Section).

If you have them intentionally in Raid mode, you're array may not be compatible with the new chipset. This typically happens when transferring from another type of raid controller, like Intel to AMD. To resolve this you need to backup the array while it is on the functional system and then in the new system, recreate the array & Initialize it in the OS followed by loading in the backup when its ready.

With respect, Disk Management isn't going to show HDDs that are not present in BIOS.
But thanks anyway.

Yes, they spin up so I know they're getting power. I know the SATA connectors work because I've swapped them with the working drives (to be sure). I know the HDDs work because they work if plugged into an external dock. The SATA connectors are all plugged in tight on the Motherboard. And... the SATA connections on the motherboard work because (again) I've swapped the SATA connectors around with the working drives.

So yes... I'm staring blankly at a brick wall here.

SSD - Samsung 850 Evo 500Gb

Is 850 Evo in m.2 form factor?
Because using M.2 drive in M.2_1 socket will disable sata ports SATA6G_5/6.
Connect your sata drives to different sata ports. Avoid using ports SATA6G_5/6.

Checked BIOS but SATA ports are enabled and in AHCI mode. And no, I'm not using a RAID setup. Never felt the need. Even turned RAID support off, just to be sure, but still nothing

850 Evo is a standard SSD. Can't afford m.2 at present, but thank-you for the thought.

Which sata ports are you using then?

 

[3vangelica]

1, 2, 3 & 4 and various configurations of those. Tried 5 and 6 too but it doesn't matter which configuration I use, the same 2 drives work and none others.

 

[SkyNetRising]

If you use same port and one drive works, other one doesn't, then second one is broken.

 

[3vangelica]

If I use Port 1 & 2 they work. Port 3 & 4 they work, Port 5 & 6 they work. And any configuration thereof (2 & 6 for instance) they work.
I've used different SATA cables for the drives that aren't showing, Swapped to the cables that I know work, but still the drives aren't showing.
It is as if the motherboard/bios isn't capable of seeing more than 2 drives, though why it picks those same 2 every time I have no idea. Currently I'm using ports 1 & 3 for the 2 drives that are working.

There must be an explanation. I'll just have to go to bed and try again in the morning. Maybe a bit of sleep will help?

 

[popatim]

Just to be clear, ANY two of the HDD's will work at a time? or it a specific two that work?

Sorry for not marking this thread closed sooner.

For the record, I opted for 2 drives only and the problem be damned!
