I spent much of yesterday at the Apple Store, which often starts out as fun but ends up being exhausting. A friend's
laptop had an accident: salt water got into the hard drive, and the
photo our tech took of it confirmed no recovery possible. I had a
laptop I no longer used so she took it in with her external drive and we
crossed our fingers as the data migration took place. So far, all is
well. But if she hadn't backed up her computer on that external drive,
it would be a sad story.
Afterwards, in the car, we talked the various ways of saving work. When she first got the bad news about her laptop, I read the panic on her face. All her creative work, gone? She hadn't ever had to recover data from an external drive (Time Machine in Apple lingo). So she didn't actually trust that it would restore her files.
