Need help for Hitachi HTS541612J9SA00 recovery

[Powermax]

Hi to all.
I need help for recovery data from Hitachi HTS541612J9SA00.
I connect it to PC3KUdma and power on. The Hdd go to ready but utility do not recognize the Hdd Family. I manual select family and start utility.
If i try to make a SA Check, i cannot have access to SA.
I try to start in Safe Mode. For start in Safe Mode i modify NVR FW boot flag from 0x01 to 0x00.
Starting in safe mode, the utility do not recognize the family. I select manual select family and start utility.
Now i have access on SA. I run SA Check. I see all module on copy0 is good and all module on copy 1 are bad.
I saved all copy0 module and i try to save it to copy1. I can rewrite all module on copy1 except PSHT and RSVT. Now if i run SA check, i see the only bad module are PSHT and RSVT on copy1.
I re-modify the NVR FW boot flag from 0x00 to 0x01 and restart Hdd.
Nothing change. I cannot have access to SA and to data.
I try to use DE settend on Using Active Utility for cloning Hdd, but all sector are BLACK and i cannot read anything.
My question is..... but is sufficient have one good copy of PSHT to have access on data, or is necessary have both good copy ?
I try anything, but i cannot clone the Hdd.

Please, someone can give me some help to have access on data ?

Thank you very mutch to all.

Bye

I faced such problem many times before, i changed the heads, but this did not work, i may guess from my previous experience of this type of drives, this drive is unrecoverable.

[Powermax]

Thank you the same. Bye

Well, it may not be that way. I had a few cases that I could solve.

Have you tried to swap heads on that drive?
Have you checked the special module that references to PList?
Have you checked if PList on copy1 has any bad sector on it?

[Powermax]

For now i do not swap Heads.
I want to use that as last try.

All module on copy 0 is good.
All module on copy 1 is good except RSVT and PSHT.

I try to copy RSVT and PSHT copy 0 to copy 1, but may be i have some bad sector on it because the module write start but stop near 50% with INF error.

There is some way to bypass SA bad sector ?

Thank you

is it possible to change the address of PSHT module...
try to check in module RESF and edit this module ...
I never try this one... just got an idea.....pls correct me if i'm wrong.. thanks...

[Powermax]

Ok i can try to edit RESF, but when i edit it, what i must modify to change PSHT address ?

[dmarques]

That is an option that can be done too.

But you have be sure that there's some damaged sector.

To do so you can go to Service Information Objects and read PSHT with Ignore reading error option.
After it reads search for the damaged sector.

[steven]

pls let us know the progress

[Powermax]

Ok i readed PSHT Copy1 with ignore error setting.

I see i have some bad sector from sector 138752 (0x21E00) to to end sector 269823 (0x41DF0)

And now how can i do ?

Tnks

[dmarques]

Hi,

Now one option is to resize PList to read only until the bad sector location.

[Powermax]

Sure!!. The only problem is that i do not know i can do

[dmarques]

Please PM me.

Thank you for your Help Datalabace, but my customer have waived the recovery.
