OS X question -- missing dates on files?

[Sarcany]

You're saying that if you control-click on the "Date Last Opened" column-header, you can't select "Date Created" ...?

...Or are you saying that when you select "Date Created" you don't see any info in the Date Created column?

What version of the macOS are you running?

What is the file-system on the external drive? Is it initialized as MacOS Extended, or is it initialized as FAT?
