In addition to my last mail. I did the dd, got the image in a file, ran xfs_repair on it to recover my data. I am all sorted now as far as data is concerned. Now, I want to create xfs file system again on that partition, but I cannot find an option to scan and mark bad sectors during mkfs.xfs runs (or any other command related to xfs). I want something like what -c option does in mkfs.ext3. Thanks from Vijay
