Scratch disk full message

[Keith28306330fxxr]

I have Elements installed on a relatively old (2017) Surface Pro. Originally when I purchased and installed Elements the Surface had a 128GB SSD drive (drive C:). Over time this became nearly filled up, and I added a 512GB SD card in the available slot (it is drive D:). When I load photos, it gives me a "scratch disk full" message. When I attempt to change the settings, only drive C: is seen as available for a scratch disk. Are there any other settings I need to change to have Elements recognize the additional storage on drive D:? I could obviously move stuff from C: to D: to clear space on C:, but the settings show that up to 4 drives can be selected as scratch disks, but mine only shows drive C:.

SD cards are notoriously unreliable when used as computer storage. Don't think of moving anything there unless you have a backup. I doubt Photoshop could use an SD card as scratch.

Hi, thanks for the response. I didn’t expect the software to know what kind
of storage, just that it was another drive since it had the next available
drive letter. I will try to install Elements on my wife’s PC, a newer
desktop with multiple and actual hard drives to see how it works. She has a
better monitor, anyhow!

@Keith28306330fxxr, I have a lot of drives on my computer and it takes the program a while to recognize the available scratch disks and show the sizes.  While I doubt that is a problem with only two drives, it sounds like the age of your machine may be a factor in its peformance.
