Deleting TimeMachine backups from an external drive is not creating more space on the drive
I have a 1TB external drive that is filled with old TimeMachine backups. As I delete the oldest ones, I do not see any gains in space on the drive. I want to create space on the drive for other uses.
How do I recapture the space that was occupied by the now deleted TimeMachine backups?
Thanks
