lost hard drive permission to read write on my desk top mac

I was trying to upload a file which won't work. In troubleshooting I found my permission as admin is read only. This was not a problem before (don't know exactly when it started). System says read write but not admin. It won't let me change it with my password.

iMac 21.5″, macOS 10.15

cannot change permissions on Seagate harddrive I've done Cmd+I (get info). It says I have read and write access. I've opened the padlock.

I'm just trying to drag/drop some photos, but it's not allowing me in. Please advise.
