Hitachi HTS545050

[barak]

Hi gurus,

I have a Hitachi HTS545050 which becomes ready in PC3K normally. When trying to clone it has a lot of bad (or at least not read) sectors.

SA-structure test shows some odd things though. Any ideas?

Is the pcb native?

[fzabkar]

The mu-code of the RESF module (C67G) does not match those of the NVRAM and RAM0, OVR0 and OVR1 modules (C60F). FWIW, I notice that these mu-codes match in other resource dumps. Does this suggest that the RESF module is not native? If so, and since the SA modules seem to read correctly, would it be worth changing the mu-code of the RESF module and writing it back to the SA?

AFAICT, the NVRAM should contain the drive's serial number.

I hope I haven't introduced a red herring, but does the fact that the size of the PTRT module in bytes exceeds its size in sectors constitute a problem, or does the former merely reflect the amount of RAM allocated to the module?

Code:

------------------------------------------------------------------------------------------------------------------------
ID  : Copy : Importn.:    ABA   :    ABA   :  Size :  Read :  Size  : Address in : Read :   Hdr : Description
     :      :         :          :(original): (sect): (sect): (byte) :     RAM    :      :       :           
------------------------------------------------------------------------------------------------------------------------

PTRT :   0  :     B   : 7FE200D1 : 7FE200D1 :    2  :     2 :   1568 :  00003FE0  :  Yes :    Ok :
PTRT :   1  :     B   : 7FE210D1 : 7FE200D1 :    2  :     2 :   1568 :  00003FE0  :  Yes :    Ok :
PTRT :   F  :     B   : 7FE000D4 : 7FE200D1 :    2  :     2 :   1568 :  00003FE0  :  Yes :    Ok :

Hi,

The pcb is native. This patient has been earlier on a common computer shop for software data recovery. AFAIK they have no tools to modify modules. This seems to be quite odd.

[fzabkar]

Perhaps people would be able to help you if you were to upload the drive's resources.

[barak]

Yes, exactly. Stupid me. Which ones do you mean?

[fzabkar]

Why not just upload the lot, ie NVRAM, ROM, and SA copies 0, 1, and F?

[pcimage]

@OP...

It can read "some" sectors though, right?

[barak]

Yes, some are read fine. But just some.

[barak]

Here are firsr nv-ram and rom (as txt-files).

Why don't you ZIP or RAR your files as BINs rather than TXTs?

BTW, I can see that the serial number is "Q7CRGRGL".

[barak]

Just a moment.

Yes, that's correct. The serial number I mean.

[barak]

Ok, finally I got it.

Yes, some are read fine. But just some.

Then I expect the PCB and NVRAM are original.

I suspect you have weakened head(s) and/or severe media issues.

[barak]

Yes, everything is original. Most likely heads just like pcimage concluded. This odd sa structure test confused me.

Thank you everybody for your time and comments.
