Hitachi HTS541616J9AT00 and a new PCB - how to access ?

[bumblesVoice]

Hi there,

my Hitachi HTS541616J9AT00 is dead. The drive is silent and not spining.

I´ve bought the same PCB and will read the old NVRAM ... I´m hopefull to re-programme this into the donor PCB.


But, how can I get access to the PCB ? (some software ?)

The "HD Doctor for Hitachi/IBM Software" will not work without special hardware ??


Thx for any answer

hi
you may access data with professional tools but you can also read with a flash programmer or simply swap the NVRAM chip - if you 're sure the PCB is compatible and the content of NVRAM is ok.

Hi,

1) "using a tool" sounds easy - Is there any without some further hardware ? The hdd itself is not accessable now !

2) "read with a flash programmer..." - Is there a way, i can do it without solder ? Reading the old NVRAM chip and writing the new ?

3) "simply swap the NVRAM chip". - the PCB has the same codes; it has to be compatible. But I can't be sure there is no damage in the old NVRAM chip. The HDD has been in use and stopped spinning without any recognizable reason. So, with that idea I have to use my soldering iron ? - There is no chance simply swaping the PCB and the job is done ?

This model have unique adaptives inside the NV-RAM.
Simply replace of the PCB is useless.

You need HW and SW like SD PC3k ...

No you need to desolder, read and write on another to be soldered on the donor PCB

3) "simply swap the NVRAM chip". - the PCB has the same codes; it has to be compatible. But I can't be sure there is no damage in the old NVRAM chip.

I think soldering iron should be not a problem if you have to deal with PCBs

May be you can check for a PRO in your area if data is worthy

Hi,

thanks for yours answers !

1-2)
Sade. I hoped to be on the 0,01% lucky side.

3) ....

I'm afraid about the data on the NVRAM chip. Apart from the soldering itself, is there something I have to know before ? There is nothing around the chip necessary to refresh the data regularly ? - Or something like that...

I think you should get professional advice from a established DR firm.

If you are this unsure, then attempting to make any repairs could be a disaster.

Also, are you even sure the PCB is the problem? There are a number of situations where a failure other then the PCB can prevent spinning.

Of course this would be the easiest way. To give my HD out of hand, however, is the last option.

Outside the Hard Drive, behind the IDE port, there are no mistakes. The rotary engine can still be defective. Then, the HDD must be submitted.

As long as the chip only needs to be replaced, I'll try it for myself.

So again: The chip will not lose its data after (during) the resoldering ?

It's not going to lose the "data" per se, but if it gets damaged that the "data" is inaccessible because of broken pins or corruption, then data recovery costs double or triple easily.

Tough call...

Not unless you do a bad job
