google 查一下文件系统相关的 ，一般都有数据恢复的办法，比如 ext3 reserfs xfs jfs 等都有自己对应的。

gddrescue

the GNU data recovery tool
it copies data from one file or block device (hard disc, cdrom, etc)
to another, trying hard to rescue data in case of read errors.

gddrescue does not truncate the output file if not asked to.
So, every time you run it on the same output file,
it tries to fill in the gaps.

The basic operation of ddrescue is fully automatic.
That is, you don't have to wait for an error, stop the program,
read the log, run it in reverse mode, etc.
If you use the logfile feature of ddrescue, the data is rescued
very efficiently (only the needed blocks are read).
Also you can interrupt the rescue at any time and resume it later
at the same point.

Automatic merging of backups: If you have two or more damaged
copies of a file, cdrom, etc, and run ddrescue on all of them,
one at a time, with the same output file, you will probably obtain
a complete and error-free file. This is so because the probability
of having damaged areas at the same places on different input files
is very low. Using the logfile, only the needed blocks are read from
the second and successive copies.

The logfile is periodically saved to disc. So in case of a crash you
can resume the rescue with little recopying. Also, the same logfile
can be used for multiple commands that copy different areas of the
file, and for multiple recovery attempts over different subsets.

gddrescue aligns its I/O buffer to the sector size so that it can be
used to read from raw devices. For efficiency reasons, also aligns it
to the memory page size if page size is a multiple of sector size.

不知道是否符合你的要求

ext3grep？好像是有一个这样的东西。
