Blue WD40EZRZ 4TB - can only see 2TB

WD Internal Drives Desktop & Mobile Drives

My system is an Acer M3800 desktop running Windows 7 SP1 64. Just installed a Blue WD40EZRZ 4TB drive as a second drive for the purpose of storing movies and music.

I made the drive a GPT drive, but it only shows as a 2TB drive. I updated both the Acer chipset driver and the Acer Storage driver from their website, but still the same results.

How can I get the full 4TB space? I do not want to have multiple partitions by the way.

Thanks for your help.

Is your hard drive detected as 4TB within the system BIOS? If not, try changing the SATA port or SATA mode within the BIOS (AHCI/Legacy) in case support must be manually configured.

Trancer, the AMI BIOS on your Acer M3800, as you probably know, does not
specify the size of the hard drives in the system, it just shows the model
of the hard drive, and not its capacity, so there is no answer to the
question you asked me.

I don’t understand the rest of your email. Is the motherboard that Acer put
inside the M3800 desktop capable, or not capable, of recognizing the full
4TB capacity of the Western Digital Blue hard drive?

Using Western Digital’s Data Lifeguard for Windows software utility, it
recognizes the full 4TB capacity, but when Windows is started, only 2TB is
recognized.

How do we get your Acer to recognize the full 4TB capacity as a single
partition?

Thanks for your help.
