This article discusses how to repair a Western Digital hard drive with PCB 1698 or newer using the DFL-WD II hard drive repair tool. It describes a case study where the SPT value was incorrectly detected initially but was resolved by loading overlay module 11. Several modules failed to write initially due to the lack of module 13, but after writing tracks and the main ROM, the hard drive ID was detected correctly and all modules read successfully. The document promotes higher hard drive repair and data recovery rates and lists several data recovery tools available from Dolphin Data Lab.

This article is to demonstrate the hdd repair functions of DFL-WD II hdd repair tool on how to
repair western digital PCB 1698 and newer series hard drives. The following is one new hdd repair
case study but if users want to recover the data from this hdd, it's required the users have a backup
of the original firmware modules, at least the key data recovery modules of this hdd. In the end of
this case study, the hdd is restored and then write back the key data recovery modules, the data can
be recovered.

Power up the hdd;
Auto Get Details and
the SPT value cannot be recognized correctly, the correct value should be 1980 while it's now
detected as 49743 when we click 'Get SPT'; Close the current interface, click the Power button,
power off the hdd and power it on again; Autoget details and the same wrong SPT was got and now
we need to load overlay-load module 11 and after the module 11 was loaded successfully, the HDD
ID and the SPT value are detected correctly, click ok to enter the program's function interface; From
the log section, we see the errors reading module directory; Next is trying to write module 01, after
the module 01 is written, power off the hdd and power it up, auto get details, load module 11, click
ok to enter function interface, at this time, the module directory is read successfully; Next is to write
all other modules except module 01, but from the logs, we met module write errors;

2. (You must ask why the
modules failed to be written? This is because for WD PCB 1698 or newer WD drives, a direct load
of ATA cannot load the hdds normally due to the big buffer which requires the module 13 to control
it in a normal working way.) When the modules cannot be written due to the lack of module 13 and
therefore, users can try to write tracks. Next is to write tracks by ticking both head 0 and head 1;

3. After
all tracks are written successfully, close the current interface, power off the hdd and power it up
again.Enter the function interface, the log section displays module directory read error and the HDD
ID is not detected; Next is to write ROM, to write the main ROM file-ROM.bin is enough; After
the main ROM is written successfully, close the current interface, power off the hdd and power it
up, the HDD ID is detected and no error is displayed in the log section and to test the modules by
ID,
all
modules
are
read
ok.
For a always higher hdd repair and data recovery
success rate, cheers!!!
