SanDisk Extreme 1TB not showing in Disk Utility

I have a SanDisk Extreme 1 TB that used to always mount just fine on my MacBook Pro 14” (macOS 14, Sonoma). So much so that I never even really pay any attention to whether it's there or not.

Today I had to eject it because I wanted to move my laptop without having it connected, and it wasn't showing. I removed it and plugged it back in, and the OS asked me whether I wanted to allow the device to connect. I said OK and then waited, but it never showed in Finder. I opened Disk Utility, and it doesn't show there either. I have another SanDisk, a 2 TB, that I use for time machine, and that one shows up just fine. I tried swapping the cables to check, but the 1 TB still won't show. Using the same cable I was able to connect multiple other drives - it's just this one that will not show.


Am I just out of luck? Is there anything else I can try doing to see if this drive will show up? All of my photos are on it. Thanks.

MacBook Pro 14″, macOS 14.0
