HGST 12TB nowhere to be found

TrueNAS General
1

I just bought (2) HGST 12TB to try and make my own NAS. Please note that this is my first attempt. I am turning an old Dell into my NAS.

TrueNAS-13.0-U6.2
4 core i5 3.3ghz
32gb ram
Thermaltake Core V21 SPCC Micro ATX, Mini ITX Cube Gaming Computer Case Chassis
Thermaltake - SMART 700W ATX 80 Plus Power Supply

It can only see my thumb drive and a 4TB SSD. I have tried a few other HDD, they can all read, just not these HGST.

I pulled them out. Initialized on another PC, ran 1st aid, reformat, etc. Reinsertedā€¦no diceā€¦

Power supply is good, Sata ports are good, MB is good. Sata cables are good.

What am I missing?

You missed writing what exact drives you actually have.

But my first guess would be the 3.3v pin ā€œissueā€. Maybe your other PC uses molex to SATA power cables, which is one way to circumvent it, and your Thermaltake box does not?

Sorry, They are US7SAM128 - 7200 RPM SATA.

Molex is not an issue. They came with adapters, but when I upgrade the PSU, no longer need them.

Not sure I follow.

I didnā€™t say molex was the issue, quite the opposite. I suggested that molex is one way of getting around the 3.3V pin problem some people face, which would explain why the drives work in another system but not in the one you want them to work in.

You mention ā€œadaptersā€, what drive comes with adapters? Please post pictures if you can.

Btw, I get 3 Google-hits total for US7SAM128, so not exactly common place drivesā€¦ Are you sure thatā€™s the model name? The model name would likely start with an H.

My apologies againā€¦I am a bit of a noob.

HGST P/N 0f29596

The HDD does not have molex connectors. The MB doesnā€™t have Molex connectors. The power supply has both Molex and Sata. I have adapters to convert Molex in Sata.

HUH721212ALE601 type US7SAM128 Sata 6.0Gb/s 7200 RPM.

I would post photos, but I canā€™t yet.

I appreciate your effort in helping me

Cool.
But which cables do you actually use? What kind of cable from your PSU is powering your HDDs?

Does it look like this:
PSU ā†’ SATA Power cable ā†’ HGST HDD

or this:
PSU ā†’ Molex ā†’ Molex to SATA Power adapter ā†’ HGST HDD

or something else?

PSU ā†’ SATA Power cable ā†’ HGST HDD

Do you have a Molex to SATA Power adapter?

If you do, use one of your PSUā€™s Molex cables together with the adapter and see if it changes anything.

9

No Changeā€¦just weird. Even wiped and reinstalled OS.

10

If Iā€™m not mistaken the ā€˜Lā€™ means 3.3V Power Disable.
Do you hear the drive spin?
Do as @neosfusion said: Power the drive from a 4-pin Molex power connector through a Molex-to-SATA (15-pin) adapter.

Consider Kapton tape too!

Thereā€™s a summary of possible ways to handle it at:

It mentions Easystore HDDs but your drive type has the same feature/issue.

13

I use the exact same drives (HUH721212ALE601 and ALE600) and yes, they have to be powered from a Molex-SATA adapter unless you have a SATA 3.3-compliant server power supply. Which I always felt was a stupid way to go about it - wouldnā€™t making Power Disable activate when pin 3 is 0 (instead of 1) achieve the same result while retaining full backwards compabitility? Compliant power supplies would know to leave that pin unpowered, while older and consumer gear would just work. The only casualty is that Molex adapters wouldnā€™t work, but theyā€™re barely used anymore.

14

And USB adapters. And anything else which does not provide 3.3V, which the drive does not need and does not use for power. So it had to be done this way: Power ON to signal.

15

So It is now getting caught in the bios. It doesnā€™t want to load past it unless both of my 12TB HGST are unpluggedā€¦sighā€¦

16

SATA ports shared with something?

They do not. I have 4 ports non raid. Iā€™ll try and get p/n for MB later. 1/2 tempted to get a pcie sata controller and try that.

OK, so I am not sure why at the moment, but the only way I could get the disks to read is by installing a pcie sata 3 card. There must be something in the OE Bios that I am missing. I am going to investigate further.
