Lacie Won't Unmount - Applications Running

[milhous]

Yes, this is an interesting situation. Here are my environment variables of my set-up.

1. Leopard clean install and update to 10.5.2 on Mac Book Pro.
2. Backup drive is 250GB external disc in a Metal Gear Box enclosure. Nothing to do with Lacie
3. The backup drive used to be a single partition. But because the laptop is 160GB and the external disc is 250GB, I created a backup partition to mirror the size of the internal disc and ~84GB partition for scratch.
4. The volumes are named a.Backup and a.Scratch. I decided to use an "a." prefix so I remember that both volumes are located on the same physical drive.
5. Leopard-compatible SuperDuper was downloaded and registered. It was also configured to SmartUpdate and repair the disc's permissions, even though the first-run would be a backup to an empty disc. I did this so that I wouldn't have to set it up later.
6. Unfortunately, I was working on my MacBook Pro during the initial backup. But the backup completed without error. I know this isn't ideal, but I wanted to have something than nothing. I plan on quitting everything and backing up again when I leave the office.

And the output from lsof:

I opened up Spotlight preferences and explicitly added both volumes so that they can't be indexed.

I'll have to restart for now to unmount the volumes. Hope this helps.
