bad blocks on disk. Which files are damaged?

[Fionn Behrens]

Hello all...

I have a harddisk here which developed bad blocks. It is quite large and
only a few blocks seem to be affected. I ran several scans wirh the
"badblocks" tool and got a map of defective blocks out of this. Now I'd
really like to find out which files on the Reiser3.6 FS on the defective
disk are probably damaged.
Is there a way or maybe even a HowTo to tell this without huge effort?
Maybe even some kind of script or tool?

best regards, 
		Fionn

You might want to look at
http://namesys.com/bad-block-handling.html

I believe it is in uptodate state. Yes, Vitaly?

thanks for the link. The page has not been updated recently it seems but
it has some good advice. I must admit, though, that I'd rather like to
find out the defective files first and try to copy all unaffected files
BEFORE I do an fsck. Because I am afraid I could lose pointers to
otherwise unharmed files during a --rebuild-tree.

None of the tools on that page seems to be able to just point out which
files could be damaged from the badblocks list... and that was my
initial problem.

best regards,

Hello,

I never did see an answer to the original poster's question:

"I'd really like to find out which files on the Reiser3.6 FS on the 
defective
disk are probably damaged."

The bad-block-handling document doesn't seem to cover this,
how can one find out the names of files containing bad blocks?

I've seen mention of icheck and ncheck tools but 1) I can't find
them, and 2) I presume they would not work with reiserfs unless
specifically written so.

Thank you!

I guess that such files will get listed by the below command:

find -type f -exec cat {} > /dev/null \;
