SOLVED
I used ddrescue to copy the files over. It worked!!
I was able to copy my Arch & Windows QCOW2 images from my old 2TB SSD to new 4TB SSD. However, I’m having trouble copying my Lubuntu and Neon QCOW2 images. I’m always getting an “input/output error”. Even cloning doesn’t work.
The fact that I was able to copy my Arch and Windows QCOW2 files leads me to think it’s the images that were having problems, I did consider it was a disk issue, but I ran fsck, and they were fine… I also tried to copy the images to somewhere else in the the same 2TB SSD, but that didn’t work.
Any idea what’s up? The images are still usable when I boot it up.
Edit:
I ran journalctl, and found this:
