Problem with WD Marvel Demo

[Vlad]

Drive can't read DIR module and don't knows where to read rest of modules
SERVO_ERROR_CODE_BASE_SvirActSync usually points on dead HDA
Not repairable

I should also mention this. When I performed "Check all modules" in "Modules operations", it found the following modules:

• 0A - Head Map
• 0B - Flash DIR
• 0D - Firmware Version
• 20 - SMART & Log Current
• 30 - RPDList/Òöàíñëÿòîö SA (not exactly named like this because I can't tell the exact accented characters used)
• 47 - Adaptives Service Area
• 4F - SA servo adaptives

So at this point, could there be a way to create the ROM modules from these SA modules?

Посмотреть версию оверлея в 4F - SA servo adaptives, зайти на http://files.hddguru.com/index.php и поискать там свою версию как донора оверлеев и дира
Потом загрузить оверлеи донора в память.
Загрузить Дир с донора в память.
Проверить читаемость родных модулей.
Проверить головки.
Если есть не читающие головы заместить их на читающие головы в памяти.

Sorry, I don't understand what you're saying.

You don't have SA modules
0A,0B,0D,20,30,47,4F all of them, are ROM modules

Ah! Then in this case, can rebuilding the SA modules from these ROM modules be possible instead? I remember reading this article that it's possible to use ROM modules to rebuild the ATA Overlay modules instead of rebuilding ROM from SA modules though that article is with HD Doctor which I don't have access to. I do wonder if that's can work with WDMarvel and if so, how?

Also, this is what it looks like when the ROM modules were found:

[Vlad]

What do you want to rebuild?
I said you, SERVO_ERROR_CODE_BASE_SvirActSync means that HDA most probably is dead
Disable all heads in Head map editor except 0
Restart drive
Try to read Modules
If still SERVO_ERROR_CODE_BASE_SvirActSync, then disable head 0 and enable head 1
Try to read modules on head 1
Test all heads in this way
If all heads gives SERVO_ERROR_CODE_BASE_SvirActSync, put drive in the trash, it is not repairable

In this case, how do I access the Head map editor to disable and enable the heads? I checked out "Heads" >> "Edit head map in ID0A". I can't find anything for testing each head. Did I look somewhere wrong?

Also, I'm trying what I can to recover data from the HDD by either rebuilding the ROM modules or rebuilding the ATA Overlay modules based on the article I shared. The HDD sounds like it has no problem spinning. The heads doesn't sound like it's stuck. If necessary, I might have to investigate the heads according to this YouTube tutorial.

I describe how to test heads in previous message

Disable all heads in Head map editor except 0
Restart drive
Try to read Modules

Repeat for each head
Any manipulation with ROM doesn't resurrect dead heads
