 | | Reading a filesystem's data structures directly off the disk is not inherently difficult, but is hindered by the fact that there is very little documentation available on the structures used to implement the filesystem. A number of the fields in these structures are stored in various units (e.g., filesystem blocks), and must be converted to other units (e.g., disk blocks) to be used. The units used, as well as the formulas to convert them, are not generally documented. | |
