数据恢复，fsck的问题

[wfnh]

因为我的一个误操作，将一些资料rm了，现在想找回来，于是我对/home做了dd，dd if=/home of=/media/data/home.img（我本来的home分区是reiserfs的）

然后，我mkdir /media/chk 再挂载上chk目录：sudo mount -t reiserfs -o loop -w /media/data/home.img /media/chk(这里应该是以读写方式挂载的吧），

再fsck一下：sudo fsck -t reiserfs -fr /media/chk

问题出现了，发生以下错误：

Will read-only check consistency of the filesystem on /media/disk/media/chk/
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes
bread: Cannot read the block (2): (Is a directory).
reiserfs_open: bread failed reading block 2
bread: Cannot read the block (16): (Is a directory).
reiserfs_open: bread failed reading block 16

reiserfs_open: the reiserfs superblock cannot be found on /media/disk/media/chk/.
Failed to open the filesystem.

If the partition table has not been changed, and the partition is
valid and it really contains a reiserfs partition, then the
superblock is corrupted and you need to run this utility with
--rebuild-sb.



就这样了，我的数据啊，希望大家帮帮忙啦，真的很重要的数据的，拜托了！！
