Partition table entries are not in disk order.

Your HDD is an old drive with SATA II interface. It's a bad bottleneck. Moving home from /dev/sdb4 to /dev/sda7 will slow down your machine again. To avoid this buy a larger SSD, which now come with a very reasonable price tag.

Another option is to go with /home on /dev/sdb4 and mount /dev/sda7 somewhere /home/username/HDD. Thus heavily used files stay on the faster /dev/sdb4 and less often used files may still be accessed easily.

If you indeed prefer to do the move, boot into Tumbleweed on /dev/sdb3 and login into a virtual console, e.g vt1. Change the mount point /home from /dev/sdb4 to /dev/sda7 in /etc/fstab and reboot.

I'm both inept and intimidated by the console. I had to reboot just to get out of VT2. Then I researched and found I could do the same by going to VT7. You've taught me something new! Next, I looked at fstab in kate, where it is editable. lsblk shows me that the UUID for /home on the hdd (sda7) is

c9554cbb-f155-4e5b-aef5-51987573e0b1

The sdb3 /home has UUID

795d9510-a37b-422b-bfca-856cc4a68170

Couldn't I just change this by editing in kate?

Your suggestion to leave those as they are led me to add a "Places" to dolphin that I labeled "Old Home" that lets me easily access docs and downloads. Also, I looked at

System Settings > Applications > Locations

that lets me modify where the system looks for docs, downloads etc. I can set that to the appropriate locations on the hdd (Old Home.) That seems like an acceptable solution. However, my motivation is conserving the limited space on the ssd. I use programs (k3b is an example) that did not come automatically in the install on the ssd. That was one reason I wanted to switch the /home mount: to run programs already on the hdd and add new programs there, too. Am I thinking clearly?

Yes, you can edit that with kate. However with a graphical login to a normal user you can't test your changes. If you made a mistake it might happen you can no longer login on reboot. Thus it's safer to use the virtual console, make the changes with nano and test them before rebooting.

With booting into Tumbleweed on /dev/sdb3 new programs will go to /dev/sdb3 and not to the smaller /dev/sdb4. For the time being there is ample space on /dev/sdb3.

I suggest you watch usage of your disks carefully and take action if required only.

I'm going to do just that. I've made this over-complicated. The only changes I'll make is to put Documents on the hdd. I have plenty of room and that is the kind of stuff that will fill up a drive. If I download any data, I can manually move it over to the hdd as needed.

Thanks again for your patience.
