Hello everybody!
I've a HITACHI HDD MODEL: IC25N040ATMR04-0 ,it was locked by my notebook.I forgot clear the password when I droped my broken mainboard!Who can help me! I use my bookpc password to unlock it by MHDD,but faild!I want onlyto use it
Thanks ! Good luck !:D

Seams to me that your hard disk has a password that requires an ATA command to fix it

Thank you ,can you tell me which ATA command !

A lot of notebooks store their passwords as keyboard scan codes. If you know the password you can convert it and an unlock program that uses hex. (I think there's one for the xbox, I forget the name). good luck.

Look in this site http://www.t13.org - you cn get there the ATA command specification 7, get all 3 docs and read them.
You will find the answer that you are asking for, maybe you will not unlock the hard disk.

Thank you very much!
I will try! I can unlock all notebookhdd firmware password but the last !
Good luck!

This is interesting, why you don't tell us how you can do this ?
There are many persons here that would like learn about this matter, including myself.

agreed, but I am sure you can do the earlier IBM drives ??

This teachnology spent my much money.If anyone had good software I would consider to tell he! Such as how to repair Seagate Barracuda ATA V bad track!

I do not want that you (jun) change your mind. I think that your position is valid. And i also think that all your decisions are just up to you.
But I would like to get you msg to help me to explain some of my comments, and I'm sorry about this too.
Ok, guys here we have what I allways say and what happens here , ( I do not need the info about password, because here in our lab we can solve 100% of passwords problems ) people come here and ask all the times for help for software and anything that can help them, and when they "THINK" that they know something they do not want to share, because they had to pay to learn for, and the rest of the persons that are here ? the gott what they know for free ? - Very inetresting. Sorry body, do not worry about the comment you are not the first to do this, and you will not be the last.
All knowledge costs money time and sometimes falmily relations ( this for me is the hightest price that I already payed in my professional life), and this is valid to everyone here that study and invest in knowledge.
Changging, changging - this is not the first case and will not be the last.
Ok, ok no problem.
