[Wlug] badblocks on ext3 fs

I've located the cause of weekly SCSI errors that I asked about a little while ago -- a backup program reads a file (not an important one) which has bad blocks. The file is on an ext3 file systems. My question is, do I use "e2fsck -c" to fix the problem? I'm under the impression that ext3 filesystems are just ext2 with journalling added, so that ext2 tools are the right ones to use. TIA, Bill
