Hi all,
I need to read the CRC value of the desired sector on hard disk. I DON'T need just to detect was there any mistake reading that sector, I just need to read the CRC value of the selected sector without reading the entire sector and calculating the CRC value by myself, ok?

Thank you all who help me with this, a lot!
burek.

    I think he wanted to know if it is FAT32, NTFS ...
    And the application you are thinking of (making, using or developing with) not the OS.

    I need to write some code in ASM or c/c++ or so, that can read the crc value of the given sector. So, the solutions like to use some other software is not what I need. Also, I've tried INT 13h,02h that reads the data contained in the sector, into the memory, but the problem is I don't need the data, I need that additional bytes (header or footer of the sector) that contain those ECC codes, crc, sync bytes, gaps, servo bytes, etc..

    Is it clear now? :)
