Asus H110M-A/M.2 Motherboard treats WD 3TB as 2TB.

[Phkzone]

I am installing a new system: Asus H110M-A/M.2, Western Digital Blue 3TB hard disk, etc.

Inside the ASUS UEFI BIOS Utility when booting the system, it shows: "WDC WD30EZRZ-00Z5HB0(2000.4GB)". Then I try to install windows 10 in it. However, windows detects only 2TB too.

In the BIOS, I set to "UEFI driver only" already. And I am sure the disk is in GPT format when looking in windows 10.

Please help!
Thanks!

Hi there Phkzone,

That is unpleasant. 🙁

Are all the MOBO's drivers up to date? In case they are not, it may be a good idea to update those.
Also, you can attach the drive to another SATA port, that is perhaps, on a different controller.

In case the issue persists, I believe it would be nice to attach the HDD to another system, so you can make sure there's nothing wrong with it.

Let me know how this goes,

update your motherboards BIOS in BIOS itself using EZ-Flash. Don´t flash in BIOS

I tried to plug it into another sata port, but it looks the same 2tb size in the bios.
And I don't have another new computer to test it. My old one is bought from 10 years ago...

Did you install windows in UEFI mode?

You could enter the disk management and extend the other 1TB to the existing one

I install the windows 10 in UEFI mode already.
The main problem is only 2TB shows in BIOS.

Please have a look at the label of the HDD, be sure it´s "WDC WD30EZRZ-00Z5HB0"
and not "WDC WD20EZRZ-00Z5HB0".

So in disk management of windows the missing 1TB is not there too?

Have a look for unallocated space.

Bios version is 2003? reset BIOS by clr cmos jumper (look at the manual how to)

Thanks all for your help. My motherboard detects 3tb with a strange method:
I plug the 3tb drive into my 10 years old system (945g). The BIOS can detect it as 3tb and surely the windows 10 do not starts. Then i plug the drive back to the new system and it can detect 3tb now!!!!!
I don't know how it works!!
By the way, thanks again!

glad it´s working now

some more questions:
did you power up the new pc without the hdd in the meanwhile
or did you plug in the hdd into a different sata port
or did you unplug the power cord of the system or switch the on/off button on the psu?
