Fig. 8.3
Here you should click the 'Start procedure' button, monitor the terminal output
, and connect the appropriate points on
the controller board when the HDD displays the
F3 T>
prompt. When the drive reaches readiness, remove the
connecting tool and click the 'Ready' button.
The mode can be also quite convenient for bypassing of some other LED locks. In such cases, click the 'Cancel' button
as soon as access to terminal is obtained, then proceed to the analysis of drive status via the terminal.

O
perating principle of the main part of the unlocking procedure
This part of the algorithm implemented in the utility does not require user participation; it is described here for better
understanding of the processes in the HDD being unlocked.
When one of the lock bypass algorithms (spindle motor insulation or short connection of the read channel) completes,
the utility analyzes service information, backs up the HDD modules and ROM, resets S.M.A.R.T. and overwrites the
translator module. This sequence allows it to preserve the original drive condition (except for CE-log) and skip the
translator recalculation step.
Attention!
At present the majority of HDD after Self Scan pass post-processing consisting of logical scanning with
relocation of defects beyond P-List. As a result, translator recalculation based on P-List (described in articles available
in the Internet, used in the previous revision of our suite and the Salvation Data tools) will end up in translation
mismatch and inaccessible user data beginning with a certain LBA. Automatic solution for the translation mismatch
problem is implemented in our utility, you can invoke it from the menu '
Tests → Service information → Work with
service area → Recover translator'
(for details please see
section
5.5, Host system detects a HDD, drive beginning is
visible but starting with a certain LBA continuous space until the end is filled with UNC errors).

It is easier to monitor the situation using the RxD indicator of the PC USB Terminal adapter instead of the terminal
window: when it starts blinking frequently it means that the drive returns the command mode prompt. The adapter
can be conveniently placed near the HDD within the field of vision while examining the connection points.

We should also mention that translator corruption resulting from G-List appending in case of writing problems
becomes increasingly frequent and can be encountered independently from the LED: CC lock because of CE Log
overflow. The problem at that may be initially manifested as zero capacity in the HDD ID.
