Hello again people,

So, I have a small issue.

Currently I am using a 4TB external drive for a Time Machine backup for two internal drives. One is my startup disk and the other is just general storage. Recently I got a new 3tb internal drive and cloned my old startup disk drive to it. I no longer need to back up the old drive, only the new one. When I select that I don't want to back up my old hard drive, it still keeps the previous back ups of that drive on my external drive.

My question is: How do I remove the backups of the old drive and replace it with the new one without having to start over again? (it took 26 hours to back everything up and thats loooooong)

Sorry if its confusing!
