What motherboard do you have in your rig?
Might be a chipset or SATA Controller driver issue?
Have you updated your BIOS to the latest version?
I have a Gigabyte X58A-UD5, with firmware FA.
I don't think so, as I am using the same port and cable as for the other drive and that one was fine.
I have just updated the BIOS to the latest version, Fe5. Once back into Windows it detected a lot of hardware ports again. After a second reboot I checked the Disk Management and the drive is recognised properly with the size it is supposed to have, 3725.90GB. Thank you very much for the hint. I haven't updated the BIOS since I bought this motherboard 3 years ago. I'm always hesitant to mess with the BIOS upgrades.
Gigabytes website listed for this firmware Fe5 added support for 3TB+ drives.
Have you tried it with the same cable and SATA port as with the working drive? And have you tried it without the working drive?
Yes, I have tried both. Unplugged the good one and plugged in this drive.
Where did you order the drive from?
I purchased both drives from www.alternate.de. I pretty much get all my components from there.
I'd suggest you make sure you have up-to-date disk management drivers (probably RST). I rather doubt it is the drive itself. Just googling and I see people with exactly the same issue for 4TB drives and exactly the same size cutoff you listed.
Also, does your BIOS report the full capacity for the disk? If not, it is more than likely a BIOS issue and not a driver issue.
I couldn't find a place in the BIOS that reported the capacity, it would only show me the product models.
In short, I updated the BIOS with Gigabytes @BIOS tool and the drive is now being correctly detected and I can use the full capacity. Many thanks for your quick help!!! It is really appreciated
