Sorry I did not write all the details of the project immediately. I'll try to explain my project. The present system has no utility statistic errors for disk devices that is not convenient for analyzing faults disk as a result unstable operation of programs. I propose to develop a system based on command iostat -e or-E (depending of the desired information) for these statistic, also using existing and available information in the utility. For testing changes I propose systematically analyzing disc errors that are not yet classified, and then compare the quantity of these errors and the number of detected.
