Talk:Identify damaged files
the exact number to use in the seek - how is this arrived at - is it a block number directly from the badblocks output? Is it calculated from those block numbers?
- To make the harddrive transparently map out the badblock with a spare good sector you will have to simply write zeros to the bad block using the dd command as root. Remember that with this command you have to work with the same block size as your filesystem and the block as to be relative to the partition the filesystem is on and NOT the harddrive as a whole:
- dd if=/dev/zero of=/dev/sdxy bs=4096 count=1 seek=2269012
and this piece: " NOT the harddrive as a whole:"
Btrfs section may need updating
My btrfs scrub gave the following warning:
