A friend has just had a break-in, and - not content with stealing the things he'd worked hard to get - the robbers put the entire contents of his hard drive online. On hearing this I changed my settings so that my MacBook would lock a few minutes after sleep. But what about my backup drive, a FireWire external hard drive, which contains all the same information. Can I set this as locked, and to open only with my admin password? I'm using an Intel-based MacBook running Leopard, I think it is - the latest OS, anyway.
