Yesterday I tried to install a 3G datacard while ridin’ a train. Didn’t go particularly well. Computer hung and I had to reboot a couple of times until I gave up.
When I got home I tried to start the computer with no success. It wouldn’t start xwindows and it wouldn’t mount /home. It felt impossible to have the second hard disk corruption in two days, but I tried everything I could think of. After about 5 reboots everything came back up and has been running perfectly ever since. Scary. I will start to work on some sort of backup pretty soon.
