WD20NMVW-11AV3S2 With PCB Sata became slow in PC3K

[infofaster]

Hi guys,

I have this drive that have heads damaged and i swap the heads and get a PCB Sata with the same MCU and same engine chip and i put the ROM chip original to the PCB donnor, but when i connect in PC3K the drive became Ready and spinning but can't read the ID. Any thoughts about the problem? Damaged ROM?

Thank you in advance

Could it be that user changed PCB?
Maybe he forgot to remount original pcb onto hdd, in this case ROM wouldn't be the original one.

Can you access to SA at the moment?
Have you tried to boot with LDR?

I dont think the PCB was changed.. at the moment i select auto detect familiy in the initial menu but cant detect the familily and try to read the HDD ID, can't even try to enter in kernel mode.. i will try to search a compatible LDR to load in the begining and see what is the reaction. Thanks for the reply

Well,
You Never Need To Unsolder ROM From Patient USB PCB And Then Solder It To Donor SATA Board .Your Tools Can Handle ROM Reading From Patient USB Port To Donor SATA Board .Also There Are 2 ROMS In USB PCB One is The Actual ROM And The Second One Is The SATA To USB Bridge ROM

PS : Hope You Have Transferred The Right One To The SATA Board

Yes i know but i don't like to write logically the ROM in the past i made mistakes so i like to keep the things physically. I Swap the U12 ROM chip its the right one, right?
