1TB HDD showing only 3.90 GB free space

[rosenaaron]

My 1 TB WD Blue HDD is connected to my PC via SATA to USB (for formatting). I tried to install Windows 10 on it using a different PC, but ended up just wanting to format the drive, however when it shows up on my computer as the "I" drive, it only shows 3.9 GB. I have tried to format it again, and I clicked "restore device defaults" but it still only shows 3.9 GB. I also checked if it needed drivers, but they're updated apparently. I feel like the HDD is only showing a partition of the drive to my computer, how do I view the whole TB? Trying to sell it, so I don't want someone to think I slapped a 1 TB sticker on a flash drive lol. Help!

You want to go in to Disk Management. From there you can see exactly what partition information is.
Here's a link on how to get there

If that's not working, you may have to get a bit more in depth with Disk Part to clean and reformat it.

In Disk Management it showed it only has 3.90 GB. I then used diskpart.exe, it shows it has 931 GB like it should. I selected and cleaned the disk using diskpart and now it doesn't show up in disk management or explorer, but still shows up in diskpart.

NVM thank you so much for the info, I ended up creating a new volume in disk management, it was hiding.
