My laptop disk died on Friday.
Although this is a sad occurrence, I was very pleased to find out that my backup was in good shape, and I was back in working conditions 30 minutes after the accident.
I don't regret buying a 2 TB firewire hard disk.
That made a huge difference. Last time that I had a breakout, restoring 50GB from a USB external disk took about 5 hours. Transferring the same amount of data through a firewire interface takes now less than 25 minutes. I love technology!
