DFL-WD II hdd repair tool helps more and more PC repair companies and data recovery engineers
to restore their damaged WD drives and get the lost data back. The following is one hdd repair case
study-Head Depopping-Cutting Head 0-PCB 1640 Series. HDD basic info: 1 platter, 2 heads,
PCB1640
Steps to follow to depop head 0:
1, Write down the TPI and CAP value by
reading the factory info;
To write down above two values is for setting the TPI and CAP manually if low-level formatting
cannot be run after depopping. H0 H1 HdMap TPI = (14) (4) (0) (0) (0) (0) (0) (0) HdMap Capacity
= (4) (4) (0) (0) (0) (0) (0) (0)
2 Clear G-list and Smart;
In the case study, the engineer viewed the G-list and clear the G-list and next is to click reset smart

2. 1 and reset smart 2.
3 Enter head map, process 0B
, wait for a few seconds until the spinning sounds are normal. Tick 'Clear Translator', change the
head number to 1 and input the logical head number-head 0 and depop; During depopping, the
program also has several seconds to execute the command, so wait for several seconds until the
spinning sounds are normal. Power off and on and re-enter the program you can find the capacity,
ID and head number are already changed.
4, We can view the P-list to see if only the defects of
original head 1(the current head 0) are left.View the
head map and you can see the head number is 1.
In the video, the TPI
and CAP were not properly displayed after depopping and there the engineer set it manually with
the info written down in the first step. After depopping head 0, only head 1 is left and therefore, the
right TPI and CAP value should be displayed like the following: H0 (Actually it is the H1) HdMap
TPI = (4) (0) (0) (0) (0) (0) (0) (0) HdMap Capacity = (4) (0) (0) (0) (0) (0) (0) (0)

3. 5, After we have manually set the TPI and CAP like
above. Next is to format with P-list and this command
will help to regenerate the translator. Until now, we
have successfully depopped head 0.
