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



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.
