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.

Hi and welcome to Geeks to Go. I will refer you to your hard drive manufacturer's diagnostics program for this. Go to http://forums.pcper....isplay.php?f=40
There is a sticky post at the top of the forum that has links to most hard drive manufacturer's diagnostics.

I forgot to say I can't use any software for this, but I must write a code that will implement that :)
So, I need some function that can read the additional data about the desired sector (such as Sync bytes, gaps, servo bytes, ecc, etc)

Thanx :tazz:

humm, seems like a homework assignment for a student in computer programming. This is a hardware forum.
