How to fix a disk problem/damaged file?

[Atsuhito Kohda <kohda@pm.tokushima-u.ac.jp>]

Hi all,

I recently noticed that /usr/lib/perl5/XML/Parser on my
Debian/Stable (UltraSparc) seemed to be damaged.

~$ ls /usr/lib/perl5/XML/Parser
ls: /usr/lib/perl5/XML/Parser: Input/output error

And I failed to reinstall libxml-parser-perl_2.34-4_sparc.deb
with the same reason.

How can I fix this problem safely?  

I have expanded libxml-parser-perl_2.34-4_sparc.deb in a working
directory and got clean usr/lib/perl5/XML/Parser directory.

Is it possible and safe to 
mv /usr/lib/perl5/XML /usr/lib/perl5/NA (or something) 
and 
cp -a ~/work/usr/lib/perl5/XML /usr/lib/perl5/ ?

This machine is not i386 so I can't use Knoppix ...

Will this cause boot failure when fsck'ing ?
Thanks inadvance.
