It slays me that Macs can be this simple. So are they?
Like, once I drag a file or program into the trash and empty trash, they're gone, right?
For example, I'm converting lots of MP3s to AAC format and then deleting the MP3s by sending them to the trash and emptying trash. They're gone, right? Not taking up room on my computer, right?
It amazes me it's this simple.
not sure about the OSX, but with past versions, no.
the info still clung to your hard drive and could be recovered. when i had a mac, i used norton every month to "wipe" my HD clean.
I believe it still works the same way -- when emptying the trash, the data is still on the hard drive somewhere and stuff can be recovered until it's written over. But to ease Pete's mind, no, the stuff you deleted isn't hiding somewhere taking up space.
The data is still on the drive, but the OS isn't recognizing it in its file system (on OS X it is usually HSF Journaled...) and the sectors on the drive can be overwritten with new data. Unless you know how to wipe a hard drive completely clean -- and this is really difficult, even for someone who knows what they are doing, the data is still on the drive. It's why lots of people doing illegal things with their computers get busted... They may have erased the kiddie porn, but the forensics guys can still find the traces on the hard drive...
FYI, Leopard (OS X 10.5x) added a great feature called "Time Machine" that creates automatic backups for you. If you set yourself up with an external drive, it will automatically do the backups, and it makes it much less likely that you delete important files by accident.
