Cross post from Windows 10 OT.
So I put together a new PC and my HDD reads only 250GB rather than 1TB.
I tried disk part, disk management to allocate the drive space and for whatever reason it won't list the correct drive size. AHCI mode is enabled in the bios, didn't do anything there. I have the latest MB bios, device drivers and still nothing.
