What is reiserfsck telling me?

[Guillermo Torreiro]

Hi!

I run reiserfsck to check a partition and this
happened:

<-------------reiserfsck, 2002------------->
reiserfsprogs 3.x.1b

Will read-only check consistency of the filesystem on
/dev/hda7
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to
type Yes):Yes

So... ok, I got a problem there with block 11434, I
can't read it, but why? what is that mean? block 11434
turned to be a bad block? Can I find a work around to
this so I could get to read that block? Anyone can
explain that to me? How do I proceed with this kind of
problems?

Best Regard,

Guillermo

First it indirectly tells you is too old ;)

Now it tells it cannot read block 11434.
Likely a hardware problem, e.g. bad sector.

Well, if block is bad, it is bad. So you just cannot
read from it.
If it would be possible to read, you won't get the error after all.
You might hope that not all of 8 sectors making up this block are
broken, though.
Try to read this block with something like dd in 512b chunks.
