Strange behavior: Badblocks go away ;)

Strange behavior: Badblocks go away ;)

Hi,

Corresponding to that:

I have had some badblocks and wanted to fix them. The only real Problem
was if an 

"e2fsck -f -n -l bblist /dev/md0"

On a mounted RAID Device will make damage to a file system. If anyone
knows an answer to this, i would be real happy :)

Anyways why i open a new thread:
Yesterday the PowerSupply in the computercenter, where my server stands,
was broken and my server was unwillingly rebooted. Because it was a
power failure, the raid had to resync. After that i took a look in the
syslog (kern.log), and there wasn't any hint on badblocks (like an
uncorrectable error on /dev/hda1 etc.) So it seems that the badblocks
went away....

I'm happy but i still want to know where they are, and if they come back
;)

Any hint is useful! :D

Greetings,
Stephan
