Microsoft's Zune music player has barely seen store shelves, but it's already taken so much flak that I'm starting to feel a little sorry for it. But only starting, and in my most recent MacNotables podcast with Andy Ihnatko and Chuck Joiner, we expressed our incredulity that Microsoft could have released such a collection of compromises, confusions, and crashes, all bundled into a plain brown package. I can't pretend you'll learn anything useful from this podcast (unless you need ammunition for your own Zune target practice), but we had a heck of a good time recording it, and I think you'll enjoy the result.
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
