Hello friends, i have a case, and i need some help.
Drive:WD30EFAX-68JH4N0 (SMR)
Family:Venicer
Head Mapin ROM:0-2-3
I have an unlocked PCB, and i use MRT Pro.
The problem is:
The drive after spinning up, i hear some normal head movement, two times restarts itself with original, and with unlocked PCB then spins down.
What i have tried so far:
-Disabling loading 02 module in ROM - The drive after spinning up, two times restarts itself then spins down, and can't upload loader
-Disabling loading 30 modules in ROM - I can upload loader, but no SA access (because there is no SA translator loaded i think)
-Disabling 411 module in ROM - Drive spins up, and goes DRDY. I can upload loader, and i have SA access, and can save both copies of SA modules. But when i try load 02 module, then the drive restarts itself, but loaded loader is still in memory. I can upload 02 module with "Establish a virtual start environment" method, but the drive restart itself, when i try upload 03, or 6F module.
-Disabling refresh of module 190 - The drive after spinning up, two times restarts itself, and can't upload loader
-Closing SA access in ROM - Drive spins up, and goes DRDY. I can load loader, and i have SA access (after i opening it in RAM), and can save both copies of SA modules. But when i try load 02 moudule, then the drive restarts itself, loader cleared from memory, but i can upload again. I tried this with enabled, and disabled 190 module.
-Changing SA (ABA) regions - The drive after spinning up, two times restarts itself, and can't load loader
-Head map in RAM after i upload loader - .....cause the drive restarts itself. I note, when i try soft reset the drive with uploaded loader, it always restarts itself.
-Tried with another (newly generated) 02 module, but the drive not comes to life. Two times restarts itself then spins down.
-Tried with same microcode ROM and changing ROM modules one by one, but the drive not comes to life.
-Tried with same microcode ROM without changing anything, but the drive not seeking SA, it simply two times restarts itself then spins down.
-Tried clearing 02 module with "drastic" and "simple" method (and old method to solve slow response), everithing is a same.
-Tried above methods with another loader with same microcode, but the drive not comes to life.
As i seen, 32 relo list module is clear, and there is nothing starnge in ROM, or any other checked SA modules.
