Hello,

I needed to recover the partition table I deleted accidentally. I used an application named TestDisk. Its simply mind blowing. I reads each cylinder from the disk. I've seen similar such applications which work with MBR & partitioning.

I'm curious.

How do they read clusters/cylinders/sectors from the disk?

Is it again OS dependent? If so whats the way to for Linux & for windows?
