I've successfully installed the Seagate 80GB in my white iBook G4, 12-inch mid-2005. Whew! By the way, this had to be done because the old drive crapped out and professional opinion was that there would be no hope of resurrection. (So note: there will be no use putting the old drive in an external housing because it's probably inoperable. I'm hoping for another way... read on.) However, before it failed, I made a disk image of it and also made a direct drag-and-drop copy of the computer's folders to an external Glyph HD, and also to a newer MacBook Pro. Perhaps that wasn't the best method, but it is what was done. I intend to run Tiger (OS 10.4. ) on the iBook; that's what it ran before. (Newer computers will run newer systems.) I have all the original system discs. So, the question is, what are the next steps? I think I would like, if possible, to simply replicate the old drive (how and where things were filed, my few applications, their settings, favorites and bookmarks) onto the new drive - to make it as if, to all appearances, nothing has changed (except of course the greater capacity). But perhaps this isn't the best thing to aim for; perhaps one is best advised to do a fresh install to a new drive (because using a disc image duplicates errors? other reasons?) and then simply copy over the data you want. But if that's the case then what about the apps, and what about important little system or library files that I might not know of? How do you use these dmg files anyway? So it's a two-part question: What is the best way to start out with a fresh drive when you have old data and programs you'd like to keep but which are socked away on an external HD? And how do I get old programs onto a new hard drive so that all the permissions and settings are recognized? Thanks!
