I picked it up badly and it slipped out of my hand onto a hard tiled floor. Then it wouldn't restart.
Thanks to IT I was able to work out that only the hard drive was broken so I bought a new one, we replaced it and it's working fine again now. But I'd lost all my data.
I backed up via Time Machine, and restoring it was amazing. You insert the start up disk, plug the back up drive in and it gives you the option to Restore From Time Machine. Click OK and that's it. It took around 2 hours to restore 150GB. EXACTLY AS I LEFT IT. All preferences, passwords, settings, even the desktop, exactly as I left it. Amazing. Stunning.
Why am I telling you this? Because you should back up right now.
