In the first and the second case the existing translator will be supplemented with the "translation forks" revealed during
the testing procedure (lost defects). In the third case Data Extractor will read data "as is" and ignore the translation
shifts; then it will build a virtual translator to access the data.
Attention!
Before any operation with the HDD service information and with the translator in particular, please back
up the service information to a separate folder in the HDD profile to be able to roll back any erroneous changes.
We should also mention that besides the loss of information about Post-Process defects
the translator can be corrupted
by addition of "extra" defects to Non resident G-List or P-List. Although the utility contains a feature clearing Non
resident G-List, using it before translator restoration cannot be recommended unconditionally. As a matter of fact, Non
resident G-List may contain tracks of HDD surface representing thousands of sectors. Thus, manual analysis and repair
of the defect lists may appear quite useful. Its structure and the methods of manual restoration will be discussed in
detail in the
section 5.5.4.1. "Delicate" work with Non Resident G-List.
"Extra" defects can also be introduced into P-
List when the command transferring G-
List → P-List (implemented only in some firmware versions) is invoked. In this
case you should use the P-List editor of the utility having located physical coordinates of the records with problems. It
should be mentioned that in case of "extra" defects translation recovery using the automated solution in the utility is
impossible because the automatic method adds defect records on its own until it reaches a complete translation match.
As a result, the utility will discover data both to the left from the translator divergence location and to the right, in the
area unreadable with regular ATA commands, output a message about ambiguous condition, and terminate the process
abnormally. In that case you should analyze the divergence area manually, correct the information about defects and
either perform the restoration procedure manually or restart the automated solution.
5.5.1.
A
utomatic translator restoration (for the entire LBA space)
This solution is available from the menu '
Tests → Service information → Work with service area → Translator →
Recover translator'. When the procedure starts, you have to select the appropriate profile for the drive being restored
and check the restoration settings in the dialog displayed next.

If the 'First start' mode is selected, the utility will suggest saving a backup copy of the service information (specific
items and the destination folder for subsequent backup procedure), disable in the SA Autoreassign, Deferred defect
hiding, offline self-test, identify the type of command used to hide defects, and recalculate the base translator. Then it
will start surface scan beginning with LBA = 0.

Factory detection of defects in Seagate Arch F3 uses several passes. The first pass occurs during the Self Scan
procedure. Subsequent passes are performed in a stand under external software control. Post-process defects are
specifically the defects revealed during these final passes. We should mention that they are added directly to the
translator instead of P-List. Therefore, when the translator is recalculated using P-List only, information about these
defects may be lost irreversibly.
