How to fix Windows 10 and incorrect DC P4500 SSD Capacity?

[EGear]

I have a Intel® SSD DC P4500 Series 4.0TB, AIC PCIe 3.1 card installed in a desktop running Windows 10 Home (GPT and UEFI BIOS have been enabled); however, Windows, and SSD Toolbox both show capacity of 1.9TB when it should be 4TB.

Is there anything I'm missing or should be configuring to get it to utilise full 4TB capacity?

Some output below from Intel DC Tool:

C:\isdct> .\isdct.exe show -intelssd

Hi EGear,

Thank you for posting in the Intel® communities.

Could you please share the full output of the Intel® SSD DCT? Please run the following command and copy the output in a text file so you can attach it in your response.

isdct show -a -intelssd

Additionally, have you tried to run a low-level format on your drive to clean all data in it and see what the capacity is afterwards?

I’ll be waiting for your response.

Have a nice day.

Hi Diego,

Attached is the output requested from isdct.

Low level format, using Acronis DriveCleanser via Intel Migration Software, is sitting at 'less than 1 minute remaining for the past 30mins' I'll leave it run as long as possible and send capacity update after it completes.

Thanks,

E

Hi EGear,

Thank you for the information.

Please let me know your updates after the low-level format process is complete. It usually takes long to finish.

In the following article there are 3 additional tools that you could use for this (low-level format): https://www.intel.com/content/www/us/en/support/articles/000006198/memory-and-storage.html

I’ll be waiting for your response.

Have a nice day.
