Hello,
All of us started where U did. If U have some interest in HDD repairing/data recovery, U have to start at the beginning. You have to have a minimal understanding of how microcomputers are built (HDD is one of them) and the basics of their work. Some familiarity with electronics is also desirable.
Furthermore U should study the ATA interface commands, protocols and get familiar with programming theese protocols in whatever programming language U know. (I suggest Assembly and C(++)).
The next step is to study basic file system structures and understand how file systems work.
To do all this U won't need to access any FW area.
If U arrive at the point that U have basic knowledge of all this, and U did some successful recoveries, U will have some financial resources to buy things that cost lots of $$$$, or U may choose to start research in this area.
I have to tell here that many guys working in this business worked really hard, spent many nights coding instead of sleeping, briefly they paid the price of knowledge.
I hope U understand.
If there are other things we can help, I am sure we will.
regards,
pepe
dear pepe
thanks you for response my question
my intention is to investigate on the subject but it costs to know of where to begin
I am in favor to 5 matters to receive to me of electronics engineer and have basic knowledge of assembler (programming in protected mode processors intel 80x86)
the subject, as I said to him before, it is that is very difficult to obtain information on this, for example in the Web consegui the maxtor program firmware to repair, from salvation it dates and I could recover several maxtor 541dx series, it is why I ask if habia some other utility for others modelso of discs
really did not go my intention to request to anybody the work to him of years, single my consultation was to know if exist some utility, since I dedicate to many hours to the warm day to this
task greetings
