Modifying the hard disk driver

Hi all.

I need to reprogram the hard disk driver so that instead of serving requests in a FCFS fashion, it will use the elevator algorithm. It's quite an easy task, I already have an idea where I need to make this modification, only I'm not sure how to run the modified driver.

Just to get a feeling how everything works, I would like to see some messages printed from the modified driver and therefore I added some printfs here and there. However, I'm not sure where to put the compiled driver so that it would be loaded. Do I have to recompile the kernel each time or can I just use the makefile of the at_wini driver?

Muito obrigado.

Oh Oh!
I use this Disk Password Protection and I also got same message and I just formatted,actually installed whole new os but luckly I didn't have importanat data on my hard disk.
you can try install new os on C/ drive perhapes you can access E:/ drive.
