I recently built a FreeBSD 4.7 Release file server that has a brand new
80GB Wester Digital 7200RPM drive in it. Yesterday the box suffered two
power outages and a possible powersurge.


Today I decided that it would be a good idea to check on the state of
the file system and the result is attached below. I was unable to clean
the file system.

I've got just two questions that hopefully someone can help with:

1) What does the result below mean? (Is my drive failing? Why can't I
clean the FS?)

2) Are there any BSD tools for reading the SMART data off the Hard Disk
so that I can see whether it is about to fail or currently experiencing
HW failure. Any other ways to sheck for bad sectors?

TIA

Andrew Cutler
