I was having some issues with my hard drive so I reinstalled Leopard and trusted the backup to work as it should only to find that I accidentally deleted it somehow while installing Leopard. I don't know how or what happened but all I know is my time machine backups are gone and I'm starting from scratch. Good news (I think) is that the time machine backup files were on a partition on a usb hard drive (which I stopped using since.) Is there any chance of recovering anything from there or am I doomed? I heard that when you delete a file, nothing is 0'd out, it's just deleted from the file list. If so this should be quite simple right? Is this software I'm going to need or what? Thank you for any advice or help.
