If multiple files are displayed for a Sys LBA, it means that some of them (the largest ones) are the so-called
Superfiles
– container files with
SubFiles
inside.
Once the list of corrupted files is created, you have to try restoring them using the utility tools and the information
about the purpose / uniqueness / structure and methods for work with various service information files. If a file is not
unique, it may be initialized with HDD commands, overwritten with a copy borrowed from a donor resource or
sometimes even recorded as a file with the corresponding size filled with zeroes. If a unique file is damaged, you
should take the steps necessary for its restoration using sector-by-sector reading from copies, information from files
with similar purpose (which may contain the data from corrupted blocks in the same or a different format). Please keep
in mind that sometimes damage affects unique files, which are not required during the drive loading procedure. For
example, the P-List file may get damaged, but in that case HDD initialization and complete access to user data are still
possible provided that the translator is intact. However, its further corruption makes translator recalculation impossible.
