Hi Guys,

Do you have any idea how can I remove ATA password from
a HITACHI HTS424040M9AT00. I have PC3K, ISA and PCI versions but either
supports this model for password removal.

I appreciate Any hint or advise.

PC3000 PCI 2.27 has this model in the list.
To unlock you have to disconnect PCB from HDA, set safe mode, read NVRAM, change byte 9 to 0x00, write NVRAM back. Then connect PCB back to drive, enter the utility and rewrite module ISEC. After that write back original NVRAM and that's it.

Hi Starling,

Thanks a lot for the reply . I'll try this and let you know
the result.

Hi Starling,

Thank you very much for the procedure. You have mentioned that
I have to write back the module ISEC, I did not find such module in
the modules list. Did you mean module ICES?
If you have this module in your data base may I have a copy?
I do not have donor drive in the stock right now.
I already have changed the byte 9 of NV-RAM from 01 to 00
and wrote back to the PCB in safe mode.

You can read original clean ICES module from Factory copy and write it to Copy0.
