The failed drive partition is indicated by the '_' underline character. In the above example _U indicates that the first drive partition on md2, (Multi-Device 2) has failed. The second drive partition on md2, symbolized by the character 'U' is still part of the md2. If the second drive partition had failed, that is hdb2 then the details would be reversed. E.g. '''[U_]''' . Placing the _ Underline second in the details.
