December 13, 201114 yr Hi, I just finished preclearing my hdd. I attach the syslog. I just want to make sure it is ok, since I am a newbie and there is a lot of info in the syslog. Is there any particular value I should always check after preclearing to confirm it worked ok? Rgds. preclear_results.txt

Do a badblocks test in destructive write mode It will do 4 passes of write/read with specific patterns to detect bad sectors. The firmware may then reassign them. Be very careful with the command line and the drive you are working on. Add the -o /tmp/badblocks.lis to the command line. If there are any in that list the drive is not a good candidate for unRAID. Check the smart logs after you run the badblocks. If there are any pending sectors, the drive is not a good candiate for unRAID. Any pending sectors may eventually lead to a failure when trying make to recover a different failed drive. badblocks -vs -w -o /tmp/badblocks.lis /dev/disk/by-id/(this is where if you use the serial number then you cannot go wrong with a mistaken drive). I have the latest and greatest badblocks compiled on my google code link. See my sig or profile for link.
