Hey guys I have 2 partitions on a single hard drive, but windows 10 will only see one partition. One partition is 2tb and the other is 1tb. The 1tb is the one not showing. I used to disk management to assign it a letter and i got it to show in "my pc", but when i click on it windows tells me it needs to formatted. I dont want to format it as i have important stuff on it that i need. When I run test disk it knows that I have a 3tb hard drive, but it only searches and trys to recover the 2tb partition. No option of recovering or repairing the 1tb partition. Also when I assigned it a letter in disk management it wasn't the same letter as before when the hard drive wasn't giving me trouble, could that be the issue? How do I recover my files at this point? This all happened, because I was trying to install a Samsung evo ssd and I broke one of the sata connections of the mother board. Also can someone link a YouTube video on how to use testdisk. I used a YouTube video to do it myself, but maybe the video it watched wasn't as accurate.

Command prompt , then type chkdsk [Driveletter you assigned]: , shouldn t need other parameters like /f since the FS is not in use.

usually it doesnt matter for data to be visible if u assign it another mountpoint.

Whats your OS ?
The disk is initialized with MBR or GPT layout?

Chkdsk doesn't work. I'm on Windows 10. Don't know what MBR or GPT mean. I took the drive out and put it in my mac and ran easeus and it found the files, but they are corrupt. What should I do now?

It's almost certainly MBR partitioned. As such, can only see 2TB of that drive.
You're clicking around and formatting the wrong things.

Can you put it back in the Windows system, and post a screencap of your Disk Management window, so that we're all on the same page.
