Premiere Pro Not Letting Go Of External Drives

[MeKevinB]

I'm not sure if this is a Prmiere Pro issue or a macOS issue. I generally work in Premiere Pro off of a very fast NVMe SSD drive. No issue there. I have a few projects on the NVMe drive and some on the internal system drive. I CMD+S to save latest changes to the project on the external SSD and close the project. I'm now looking at the home screen of Premiere Pro. No projects are open. Every time I attempt to eject the external drive in macoS Finder I'm greeted with a message saying the drive cannot be ejected because Premiere Pro is using it. That's a lie because I have no projects open. Something under the hood is not truly releasing access to the drive when it should be and while it's not an Earth-shattering problem it can get highly annoying when it happens multiple times a week. Premiere Pro has to be completely shut down before the drive can be ejected properly. Screenshot attached for reference.

When looking at premiere's home screen that also means Premiere is active.

Thanks for the reply, Ann. You see what I'm saying though, right? Think of it in reverse. If the external drive is connected before launching Premiere Pro, I then launch Premiere Pro without opening a project (it would be listed as a recently opened project on the home screen), I could then eject the drive again without any error. I wouldn't get a message saying it can't be ejected. For all intents and purposes, when a project living on an external drive is closed in Premiere Pro, that insinuates that the drive can then be ejected. When you look at it that way, it says that somewhere under the hood in Premiere it's not really closing the project fully, or at the very least not releasing access to the external drive.

There is probably something on that drive that Premiere Pro is accessing.

Do you have Sync turned off?

[MeKevinB]

If the project is closed, what would Premiere still be accessing? Is Sync a Premiere feature? I don't know what Sync is.

Ahh okay. I just tested this and it is not the issue. I went into Creative Cloud > Sync and I paused it. I then connected an external drive, opened a project from that drive and then closed it again, putting me back at Premiere's home screen. I cannot eject the drive because an error says that Premiere Pro is still access it. Sync is paused and all projects are closed. This is a local issue, nothing to do with syncing with Creative Cloud. The error message even says that to quit the application and try again. If Creative CLoud was the culprit, wouldn't an appropriate message instruct one to pause cloud syncing?

I welcome anyone to replicate this scenario and you will see what I am talking about.

I'm a Windows guy, not a Mac guy. Does Activity Monitor show what is open?
