We've had snow problems here in SW England, and one side-effect has been power cuts. We've had nine unexpected shutdowns today, and each time my Mac has been running. On the last start-up, and attempting to upload photos to Aperture, Aperture has had to rebuild the library, and several folders dating over several months, were missing. All the raw files are backed-up, but I am left with hours of re-processing to do.
One thing that is driving me mad, is that I can't create a new folder without an image to start with. Surely there is a way to create a new folder without any pre-existing images, ready to simply import new (or in this case, old) photos into it.
Any advice welcome.
My first recommendation is to get a UPS. Really, for $150, it's worth it.
Second, I don't know about folders, but you can certainly create a _project_ that doesn't have any photos in it, and import into the project. Note, in Aperture, photos go into projects (ONLY). That is the only place photos are actually stored -- in projects, not in folders or albums.
