fsck -p

This can fix minor problems!!

In a case like this, as long as the system is still bootable then the OS should detect that the drivers were shut down improperly and run fsck automatically. If it fails to boot, then you need to boot from a recovery / live CD/DVD/USB drive and run fsck on them manually. You may also need to restore some files/drivers/whatever if booting after fixing the drives fails. Normally, ext2/ext3 file systems will be pretty resiliant to power failures.

Final bit of advice - NEVER run a system without a UPS or some sort of battery backup. My workstation/server runs on a good quality UPS and it has been saved numerous times from power failures and brown-outs. My other systems are laptops and the internal battery is their own UPS so I don't bother to hook their external power brick into the UPS-served power, but just into a regular wall jack or power strip.
