Question 4TB drive showing as 2048GB. So far no go changing it to 4TB

[ozrock]

Hi,
I have a 4TB drive which shows as 4TB by Crystal.
In Disk Mgmt it only shows at NTFS GPT but 2048GB unallocated.
In Partition Wizard shows the same. When I go to resize it only allows to get smaller.
How can I fix to 4TB please.
Ultimate partition s for the drive is 2 x 1TB and 1 x 2TB
Thank you
oz

Your motherboard would probably have a discrete hardware monitor IC. This IC senses and controls the fans, and it also senses the temperatures and supply voltages. It could be that this IC is not working. Can you see the supply voltages and fan RPM when you go into BIOS setup?

Thank you so much for the reply.
Unfortunately no specs show up in my A18 Bios. Is there a 3rd party script which will show the info?

I currently use Speedfan and Hardware Monitor. A generic search for "hardware monitor" should turn up other suitable software.

Thank you fzabkar.
I did both tests and here are the results.

Fan Speed result
HW Monitor - Temps

FanSpeed shows only 1 fan however all are going.

MBR has a maximum drive size of 2.2Tb. To get the full 4Tb will require changing that to GPT. MBR won't recognise anything larger than 2.2Tb, so won't allow partition of the extra space as it's still the same physical drive.

Be careful with fans on Dell mobo's. Several models are fan specific, the wiring order is different. A standard pwm is ground-12v-rpm-pwm. Dell often uses pwm-ground-12v-rpm.
You can adapter that or just repin the fan pins in the connector.

You have to check with either the mobo print or an original fan to see whats what. This is a mobo pinout issue, so applies to Anything plugged into it, be it pump or aio reader or fan.

Those hardware monitor programs need to be "trained" to correctly recognise your motherboard's sensors. That's why I was hoping that your BIOS might have some relevant info. All that these chips can do is to report what voltages and frequencies they see on their inputs. It is up to the motherboard designer to decide which input connects to which voltage, and which inputs connect to each fan and temperature sensor. Moreover, since these chips typically have an input range of 0V to 4.096V, larger external voltages (eg 5V and 12V) need to be scaled down using resistive dividers. These scale factors vary between motherboards.

In case someone in the future has a similar problem adding more drives to the T3600 with Win 10 , here are the specs for the Storage Controller Driver that worked for me in the T3600 and maybe the trial of Driver Easy will work to get it installed if you couldn't find it anywhere else.

Intel version 4.3.0.1198 C600 Chipset SAS RAID (SATA) 21/5/2015
The AHCI one is
Intel version 13.1.0.1058 2/5/2014

Good luck !
