Hi. I have a Macbook, and used Leopard with a Time Machine to backup on an external HD. The internal HD started to fail, so I bought a brand-new internal HD to replace it. I want to restore my machine with the Time Machine backup I have but I have a problem. I lost my Leopard install disk -- I only have my original Tiger install disk that came with my computer. I will partition the new internal HD using the Tiger disk.. So I ask: Will I be able to back-up my files into my new Tiger-OS HD if the back-up was done with Leopard? Can I load my backup files if they were done with a different version of OS? Please help!
