Very slow WD20EZRX

[pclab]

Hi

I have a very, very slow HDD.
It's a Diablo3S - WD20EZRX-00D8PB0

It takes along time to get ready and ID. I could already make a full backup of the resources with much dificulty.
After I issue a command to read something (defect lists, etc) it goes BSY but eventually it reads.
I have tried the slow fix repair, change PCB and write ROM, rebuild ROM, etc.
I have compared module 47 with a rebuild one and it show me changes.
I apply module 47 and it doesn't ID.
Compared ROM with ROM rebuild, it show changes on comparison, but if I write it, no ID again....
Any ideas how to deal with this? Heads?? ROM??

Thanks

Hello,

Seems like this is Slow responding problem and you have to manually clean 02 module.
Please attach 02 module here.
