Windows 10 only sees 746gb on 3tb drive

Good Day everyone,

This is driving me crazy. I have an old,but new to me HP PC. I decided to buy a 3TB drive to add as a secondary drive. Just my luck only 746gb show. I tried everything but all i can find on google is for intel chipsets. When attempting to run the driver it says my platform is not supported. I can not find any drivers for my pc to fix the issue.

Please help.
Thank you

Two things: 1. you must use GPT format for HDD larger then 2 TB. 2. there are mobo/cpu limitations to the size of a HDD that can be used.

Depending on how old the PC is, it may just be able to use a 1 TB drive.

As a work around to use your new 3TB HDD, you could get an enclosure and install the HDD in that and then connect it to the PC via USB cable....aka an external HDD setup.

Did you install 32bit or 64bit OS --- www.PCIDatabase.com -- for drivers or intel driver downloads => Plankton is also correct <= Go to the device manager =>Select "System" => Right Click => Select "Properties" => Select "Details" TAB => Select "Hardware ids" => Look at info: i.e. "PCI\VEN_8086&DEV_1E10&SUBSYS_05451028&REV_C4" ==> 8086 after VEN is the vendor code <==> 1E10 after DEV is the device code. USE this info at www.PCIDatabase.com to find the latest drivers for that device.
Some hardware is just not Supported. It might be a driver issue or a hardware issue. This is a Tool for finding the latest Drivers.

This is generic info that can be used to find out info on the your devices in your system and what the Vendor and the Device codes are. You will be looking "SYSTEM DEVICES" and "IDE ATA/ATAPI Controllers" drop down because that is where the Chipset info will be. most these days are Intel, but there are others.

i installed 64 bit windows 10. I am sorry i cant find what you are asking me look for.

I go to device manager but there is no system to select. Is it the IDE ATA?

Oh ok looks like its nvidia nforce

EBNUNO -- Then when you go to the "Device Manager" => "System Devices" & "IDE ATA/ATAPI"=> Nvidia Nforce Controller => right click open "Properties" => Select "Details" TAB => in the Dropdown Select "Hardware ids" --

Read Post #3 The i.e. is a SAMPLE of what you will see. => For every Driver there will be a VEN(Vendor) & DEV(Device) "Hardware ids" Use this to find the latest drivers available.

nforce is a very old chipset, and may not support drives larger than 2TB.

Is there anyway to partition the drive into 3 1tb partitions or this wouldn't make a difference?

Doesnt look like windows supports it. I created a live disk with ubuntu and used gparted to partition the drives into 3 1TB partitions.
In Linux i am able to access the drives and write to all of them. But in windows i see the ntfs drives but i can only access the first partition.

Sucks. Looks like i might have to go the linux route.
