I have 10.10 installed and working OK. The Home directory is located on a second 1TB disk (sdb1). Recently, I've started to experience random boot failures where the start-up routine gets as far as showing the '10.10' logo with the progress dots underneath, but then throws up an error message saying that it cannot mount sdb1. I then have an option to Quit or drop into the shell to do a manual restart.
If I then do a Ctrl/Alt/Del, the system reboots, but usually fails again. Powering off and on, sometimes more than once, is the only way to eventually get a clean boot.
The drive causing the problem is fairly new and all the diagnostic checks seem to indicate that it's healthy, so I'm not sure what causes the problem.
