Abstract
A method is disclosed for restoring apparently lost files on a computer whose directory file entries have been corrupted. In particular, the method includes an improved technique for locating initial or head clusters of files. An array is initialized to indicate that each element of a file allocation table (FAT) corresponds to a head cluster. Each element of the FAT is then examined, and the array is updated to reflect accurately those elements that correspond to non-head clusters. When all elements of the FAT have been so examined, the array is scanned to build a list of head cluster numbers.
