My sister and I are playing phone tag. She is upgrading her dual G4 1.4 to 10.3. To prepare, she is making an image of her hard drive, but she is wondering how long it should take (seems to be at least an hour so far). Is this normal? Should it take this long? Is the doing the right thing? I am a PC enthusiast and not fluent in Macspeak, but I'm posting on her behalf as at her apartment that PowerMac is her only computer, so she doesn't have internet right now.
