How can I found which disk ( harddisk) is corrupted ?

[George Magklaras]

Depends on what you mean with corruption. A failed disk should give 
read/write I/O errors. So:
grep  /var/log/messages for I/O errors. Usually these are associated 
with a device identifier (such as sda, hda, etc). Write down the device 
identifier and do a:

dmesg | grep -1 [hda, sda or whatever the identifier disk is]

You should have the failed disk.

If what you call corruption is not a hardware issue but a filesystem 
one, then again /var/log/messages should give you the filesystem and the 
device id.
