Hello!
As in topic : Hitachi : HTS723232A7A364 320 GB after heads replacement no detection.
The drive becomes ready but detection fail.
NV RAM is OK
PCB Tested OK
Heads tested on another drive OK

Any thoughts ?

Thanks in advance.

You have pc3000 UDMA or express?

MRT PRO.
Don't have UDMA yet.

Dunno about MRT, but in pc3k I would enter the Hitachi ARM utility and manually select the family.

It should then initialise the drive and give ID, allowing you to work with the SA.

I tried this on MRT and manually selected the correct family but it didn't work.

Provided it is able to load a minimal set of modules. And the load process is kindof braindead, it needs to be able to load those modules from either copy, but all of them must be intact, while not all of them would be neccessary for sa access.

I can see clearly a scratches to the outer diameter on the top side of the platter.

scratches to SA meaning GAME OVER ?

only three modules : RPSH, USAG and MFGP read successfully

That's not that much...
Especially if we consider the drive must have been able to load more modules if u were able to access the SA.

Update :

Customer told me that the IT technician in his company replaced PCBs

After he gave me the original PCB the drive not ID also but after re-identify the drive in MRT read the full model and capacity. Scanning the drive shows a lot of delayed sectors and error sectors.
DE can't identify the drive.

Any thoughts?

Were these read with foreign PCB
that's odd

Yes.

It can't be true

True or false, that's what happened already.
Why should I lie ?

I see a couple of reasons for saying it is impossible as well, but i believe what you say.
If the pcb is not native, it might have visited another firm where anything might have happened to it. Having some insight on the boot process of these drives, i would have expected a bunch of modules to be readable, because if they are not readable, the there's no sa access at all, u get abrt to each command accessing the surface.

Thank you very much Mr.Pepe for valuable informations.

Case Solved

Virtual Translator

Data is copying now.

what about the scratches you wrote above ?

Fortunately, data needed was some files ( approx. 350 MB ). And I got them all without even one error .

Don't even think I am lying. Because I don't have to.
