Anyone kind enough to share with me firmware for this drive

WD3200aaks-75L9A0

What do you need from it? Certain modules have specific SA revision requirements.

alternatively look here for generic modules

Let me know which version you need, and I'll take a look

New!! HDD-PCB.COM for all your PCB and donor HDD requirements!

Have tried all in my Db But i do not have any with the above part number it maybe the preamp but like to try a few firmware with to same part number first before having to get new heads

The model number is not important. SA version and family is. What exactly do you mean "Have tried all in my DB" ? What exactly did you try? Can you read SA? Can you determine SA version? If ROM is native you can read version in Kernel mode.

What is the symptoms? To jump from a potential fimware problem to head replacement is very risky and dangerous if you have not properly diagnosed the media.

If HDD powers reaches DRDY and spindle stays powered, it is probably SA. IF heads knock and spindle stops and HDD shows DRDY it is probably head problem. But there are variables that can affect this. Example would be damaged zone table which causes HDD to emulate symptoms of head failure.

If heads are the cause there are steps you can take to try to improve reading of individual heads, in addition to processes such as head mapping in RAM, Hotswap etc.

You clearly have not reached a confident diagnosis, or maybe you are not able to. You should write here the symptoms you have upon initial testing of the media. Also, anything you have done to the media, any SA modules modified etc

A very good explanation and advice
