I just purchased this drive. Its amazing how small, and quiet it is. I have a imac, and have already changed the partition settings to allow it to back up correctly. I was surprised that WD didn’t include info, on how to do this. At first I just hooked i up, and it appeared to work great. Luckily, I did some investigating about it, before I had problems. Anyway, I know that you can set up a password for the drive. It is so small (wallet size), a person ould just easily take it. I am physically disabled, and live in subsidized housing. The only reason that I mention this is because maintenance has a key, and things have been stolen before. I’d really hate, for this $150 drive, to quickly be placed in a pocket, and stolen. Although I really don’t have any foolproof way around this, if the drive was locked, then at least they woudn’t benefit from the theft. I could even place a sticker on the drive indicating that it was password protected, making theft less of an issue. I downloaded the pdf user manual. Apparently it is done by changing the backup software settings. Unfortunately I can not seem to find a way to acess them. Can they only be accessed, when you first plug it in? I thought that might bbe the problem, and I may have missed setup step. So I emptied and reformated the drive, turned off the mac, and unplugged the drive. I restarted my mac, plugged the drive back in, but unfortunately I still didn’t see the Smartware Settings Screen. It is backing up, based on my time machine preferences, but I can see no way to change the settings in the drive itself.
