Sudden Shutdown

I recently experienced a sudden power loss when my slack box was abruptly turned off.

After starting it up again there didn't seem to be any damage to the system.

Is there any way of checking my file system for damage.? I already ran 'fsck', but where do I check to see wether any errors were found?

Does anybody have any experience of how to handle this?

fsck will tell you if it found any errors.

What filesystem are you using? That has a big effect on what you need to do when the system abruptly loses power: if it's a journalling system (Reiser or ext3), then you're pretty much safe. The current version of either of those filesystems is fully journalling. They keep track of which files are open, as well as metadata (where the file is on the actual HDD platter, file attributes), and fsck knows how to read the journal and recover the data in the event of an error.

Yeah, if you're using reiserfs, ext3, or another journaling system, you're ok. In case of a sudden shut down, the file system isn't marked as "clean" and it was checked automatically when you booted back up. If you didn't get any errors then, you're fine.
