Opensuse 12.3 won't boot suddenly

Hi--I'm running Opensuse 12.3 on an HP Pavillion dv7 Laptop. This has happened before to me as well. Everything is running fine..I've done all of the current software updates and all of the sudden when I start the laptop I get:

Fast TSC callibration failed doing fast reboot.
Creating device nodes with udev
Welcome to emergency mode! Etc.

I am not sure but maybe it occurs after a power failure to the laptop...the battery is dead so I run it plugged in and if the power source is disturbed the laptop just shuts off suddenly.

When I view the error logs some red highlights include:

tsc: Fast TSC calibration failed

ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0

ata1.00: irq_stat 0x40000001

fsck failed with error code 4

Failed to start File System Check on /dev/disk/by-id/ata-WDC_.....

So what does this all mean? I've reinstalled Opensuse in the past to fix this and thus lose all my data.
Can this be repaired? Please help!!!
