I have old time machine backups for a computer that no longer exists. How can I cleanly delete them from the external time machine disk?

If they're on separate partitions, same method, just select the desired partition and Erase.
If they're on the same partition, you'll have to drag the appropriate Backups.backupdb folder to the trash and empty the trash. This will probably take a very long time.
Hi,
Connect a disk > open Disk Utility > select the top item for that drive in the list at the left > click on Erase.
I probably wasn't clear enough in my question. I have Time Machine backups from two computers on the drive, I only want to delete one of them. Erasing the disk would remove both.
Same partition. Thanks, I've proceeded with the delete, empty trash approach. I was looking for a feature in Time Machine that would do the deed when I asked the question, doesn't seem to be one.
