I replaced an old Western Dig. WD20EARX (2Tb) that seems to have fried with a 4Tb WD40EZRZ. Win10 Disk Management tells me it’s a 1.5Tb disk, so converted it to GPT and got my PC booting in UEFI rather than legacy bios thinking it was a partition issue…still the same. I can create a ‘simple volume’ on this disk no problem, but still only shows capacity as 1397.25GB.
Then I looked closer, and the model number shown in Disk Management is WDC WD15EADS - a completely different disk to the one in the machine! Why is my PC thinking I have this HDD installed, when clearly (on the packaging, receipt & sticker on the HDD itself) it’s not? It was bought from PC World in the UK, and fully sealed/packaged when bought, so unlikely they’ve ripped me off.
(System Information confirms I have my PC booting in UEFI mode and have converted the drives to GPT).
