Do you know why it would be that I can only choose from 2 drive letters for scratch disk in Windows 10? If I press Ctrl+At during startup it lets me select from the other 2. But, once I open a project it tells my scratch disk is full and the other drives are not listed (all are NTFS partitions).
It could be a permissions problem on your drives/partitions that is stopping Photoshop from recognizing it as a scratch disk.

There are some help pages on 'Scratch disk is full' issue
Scratch disk full error in Photoshop
How to Fix Photoshop Scratch Disk Full Errors
I know that Photoshop has a habit of leaving orphaned temp files on your Scratch drive, and they can be substantial.
They look like this. Any that don't have today's date on can be deleted. They can easily get to tens of gigabytes and beyond.
I am sorry, but I don't know the physical requirements, but it might be worth checking Disk Management to see what the partition types are. Look for the odd one out sort of thing.
We'd appreciate your feedback when you fix this so other folk can benefit down the road.
Good luck and have a great holiday.

Start PS with no files or projects open. Go to Edit > Preferences > Scratch Disks and see what is listed. All internal drives and possibly some external drives, depending on the type of external drives, connected directly to your system should be listed.
You can select any from that list then use the arrows on the right to move them up or down. Select the one you want PS to use the most and click the arrow to move it to the top of the list. select the one you want to us as the second choice and move that just below the first.
Close the preferences dialog window and restart PS.

I guess my question is not direct enough. Do you know of a solution to there only being 2 of 4 drives listed as available to use as scratch disks? Note how the question remains after having selected a different scratch disk at startup by holding down Ctrl+Alt.

Did you check the drives with Disk Manager?

This is the dialog box I get with Ctrl + Alt.
This is what shows when I click any of the downward facing arrows.
A full list of drives connected directly to my system.
The first 2 are the scratch disks I have selected in the program preference. Third and fourth show None because I haven't defined them in the preferences.
What do you see when doing that.
Please show a screen shot of the PS Preferences scratch Disk tab. Like this.

The top is what I see when I start with Ctrl+Alt held down. It allows me to select from any of the 4 drives. Once photoshop is loaded, in preferences on 2 of the drives are available to select from:
A slight wrinkle to this is that at first I couldn't get into photoshop at all.I then made space on what I guessed were the drivesbeing used so that I could launch photoshop from there and then I would it would complain that the scratch disks are full.
At this point, I have made space so that it works, but I seem to be stuck with only being able to use those 2 drives.

Are your F and G drives externals?
In the PS Preferences my T and U drives don't show and I think that is because they are external drive. Funny but the H drive does and that too is an external but it is a SSD external. The other 2 are normal rotating HDD.

They are all partitions on internal drives. All 4 are primary partitions. The 2 that appear in preferences are on the disk that contains the boot partition. D: unfortunately, is the system reserved drive that has a total of 100MB allocated. So, I really only have 1 drive available for scratch disk.
Disk manager says Healthy about all of the partitions.

Err. I don't know why an answer is marked correct. The problem is unresolved.
To quote my last post:

What happens if you move E to the top of the list and don’t select D?

Tick the "active?" box. You have both disabled.

Test Screen Name, the image in which D and E are selected, is in your post. My screen shot is in the next message and there is no E to be moved anywhere.
D Fosse, the drives that I am saying are not available, are F and G. They don't appear in the list of scratch disks.

Sorry, confused myself.
So, you say F and G *are* available if you select scratch disk during startup?
How much space is available on each of them?
Is there anything odd about the way either disk is setup?

Yes, you can see F and G in the image that I posted. F currently only has 11 GB, but when I wrote the email it and G had more than 100GB each.
Also, in my posts it is mentioned that they are all primary partitions formatted as NTFS. F and G are on different drives than C and D. C is the boot partition and D is the system reserved partition that is 100 megabytes in size.

I think that you are right. But, I haven't figure out how to apply what you are suggesting.
Taking the suggestion of someone on the thread that you link to, I changed photoshop's executable to run as administrator, and with that change I have access to the other drives as scratch disks. So, I know you are right, but I don't know how yet. If I have time, I will figure it out and post details.
Thank you! If I were someone I would make your answer the correct answer.

Well, you did credit my answer as "Helpful"and that's good enough. Anyway I'm happy that I can help someone out of a rut so that they can get their work done. I agree that an in-depth answer explaining how it works would be great, but that's not within my reach.
Running Photoshop as Administrator is a simple enough fix. Glad it worked.
Forum help is about basically getting a workable answer. I'm a Macbook owner and I don't have a full working knowledge of "permissions" in relation to Photoshop scratch disks under Windows, but I hope you can discuss that here or in the Microsoft forums to get the understanding you want.
