I have two physical SSD disks and one HDD.
One SSD is about 120Gb and the OS is installed into that SSD and by the way it has only one partition (apart from the OS-reserved).
Another SSD is about 180Gb. For now, I have cut about 128Gb from it and I want to extend the first SSD adding these 128Gb.
HDD has only one partition as well and I don't need to do with it anything.
As far as I understand, I need to move the unallocated space to the right side of the OS-drive. To do that, I also need to move the OS-reserved partition to the left, at first.
I installed EaseUS software and I don't see the way of moving partitions, everything is just locked.
Look at the following video on YouTube I uploaded, you'll see how everything looks like on my machine: https://www.youtube.com/watch?v=0D232FRMgPk
What am I doing wrong?
