disk failure

disk failure

[Vincenzo Martena]

Hi, I'm in big trouble with my hard disk.

I think there is some hardware failure, because 

reiserfsck --rebuild-tree

give out this error message:
--------------------------------------------------------------------------------------------------
reiserfsck --rebuild-tree started at Mon Apr 28 17:22:46

bread: Cannot read a block # 218118.



Aborted
-------------------------------------------------------------------------

Now the problem is that I cannot acces my hard disk, 
because the journal is totally absent. Do you know if 
there is some option I can give to reiserfsck in order to 
ignore the hardware error and keep rebuilding the tree?

Thanks a lot for your help.

P.S. reiserfsck version is:

<-------------reiserfsck, 2002------------->
reiserfsprogs 3.6.3

we are still working on badblock support in reiserfs, but it 
is not finished yet. So if your partition has some badblocks
you should dd_rescue this partition to some spare partition 
and fsck the copy. 

Alternatively, you can try to write to this block with dd, then 
the drive will probably remap this block and it will disappear.

If you need more details you can either look through reiserfs-list
mail archive or pay us for the support on the base of our 
support.html terms.

This is an old version of reiserfsprogs, get the latest one from 
our ftp site please.

Can you have the tool you write prompt the user, ask if the user would 
like that attempted, and if it works then inform the user that it worked?
