Cloned OS from Hard Drive to SSD

[Helpme]

Alright everybody. So first off, I decided to upgrade my computer, and one of the parts I decided to upgrade was my OS’s Drive. First off, I copied my old OS with EaseUS Disk Copy from a standard hard drive to a 1tb ssd and after b8uilding my new computer, it’s working fine. I’m literally writing this thread from it.

However, when I go to Disk Management, it shows i HAVE 699.13 gb on that drive “unallocated”. I assume that means that it’s not using the space on that drive, but shouldn’t it be? How do I go about increasing my normal C: drive from the 232 gb it’s got to the near 1 tb space that it has?

Secondly, I have a total of 3 drives.
Disk 2 (C which is the 1 tb SSd,
Disk 1 (F Which is the old hard drive I used on my old computer. (And seems to be using all of it’s space like it should (Though It says it’s the primary partition, which I don’t know what that means).,
And Disk 0 which is an 8tb harddrive that says it’s unallocated and that for some reasons it’s only got 7452.02 gbs of space on there.
How do I get the 8tb harddrive showing up on my computer, and why is their nearly 500 gb missing from my new hard drive?

the new drive is showing what it is because of the cloning process.
it literally clones the old space onto the new drive - so if the old drive took up 250GB, that all it’ll take up on the new drive.
you now have to go into Disk Management and increase the partition.
if DM doesn’t want to play ball, you can either get down and dirty with the command prompt diskpart or use something like EaseUS Partition Master.

and while you are in DM, reinitialise the 8TB drive to have it show up with a drive letter.
I assume it is empty.
