To put it briefly it was just a simple matter of finding Cylinder Group zero on the first drive in the array and back tracking 48 sectors. Once the RAID data offset is established we can plug [...]

We have learned what a Super Block is, a cylinder group, and some of the important data elements in those data structures. We have learned how to find these data structures by using the data elements [...]

This particular OS ran a Berkley Software Distribution (BSD) flavor of UFS. Although there are many similarities to the original file system, there are [...]
