Repair Your Seagate HDD

[mmzhr]

hi i used this command that repaired my hdds
m0,2d,1,ffff,ffff,ffff,ffff,22
m0 = user partition
2d = 101101 = enable format seacos, enable reformat zone,enable log,disable certify,enable format, enable corrupt primary defects
ffff = max write retry
ffff = max read retry
ffff = max ecc level
ffff = max rewrite retry
22 = valid key
and then regenrated translator with this command gives good performance
m0,2b,3,0,0,0,0,22

That's very good seagate locked diagnostic commands so that suchlike "kind" people will step aside.

It might be even more helpful to people to know exactly what model HDDs you ran this on. And what was "wrong" with them to begin with.

sometimes people run the wrong thing on the wrong drives, and when the drive still miraculously works, they lead others astray. You have to be careful.

This Commands Works On All F3 Series

you dont get it...

Thats what I am saying spildit.. people will just run this no matter what seagate or what issue and expect drive to be fixed. There is no context at all in OP.

i fixing drives i dont want data
i know all data will be erased
in iran people dont have enough money for recovering hdd data

mmzhr, was the computer, that the troubled HD was externally attached to, using either Windows or Linux based program? What program was that? I'd like to learn more!

mmzhr, are there any EZ-read DOCs or TEXTs for us beginners? I'd like to learn more in order to better appreciate what you hardware folks do!

Well,
i do not support seagate locking terminal commands .Just see the hell that is broken loose in ST1000LM035 and ST2000LM007 with Signed Firmware and what not

Don't you think locking stuff is obvious decision for Seagate? Based on group of silly people who shares in open sources huge amount of terminal commands and even internal documents of its description its quite ok. 99% of newbies type all commands they find without realizing their meaning. Personally I have 1-2 cases a month of customers who "tried themselves to format SA" with commands they found on web in order to recover data! And as I said above its good that typing any suchlike commands on a newer drive (which has PSID) will have no effect.

logical yes, but Holdens and Ford argument...

or John Deere argument or whatever binary argument works in your neck of the woods.

one says lock out inexperience for their own safety, other says I paid for it, I want to be able to do whatever I want with it.

IMHO you could find a million threads around the intern to cut and paste onto the bottom of this one..

Seagate can not be changed under a guarantee in Russia.
Therefore, whether you like it or not, the discussion will continue.
And new tools and methods will appear

Well,
At Head and Platter Level Already we have tools .But At Firmware Level there is Not Much That Can Be Done .This Time Seagate is One Step Ahead ,Its Not a Piece of Cake To Break The Current Rom/firmware Signed Code Man

I have no intention of trying this or any other script; I simply would like to learn a little bit about what each line does -- to better appreciate this process, and when possible, to direct individuals with certain HD problems to DR companies/specialists.

Where there's a will there's a way

That, plus I'm certain Seagate has a backdoor they put in place for their own data recovery service. Personally, I think the whole terminal lock has nothing to do with securing the drives or preventing data recovery efforts / stupid people destroying their drives. I think it's just to push a monopoly onto their own data recovery services.

I'd bet Ace and other tool makers are already running hoards of brute-force attempts to find the key to unlocking them. And, I doubt Seagate made each drive unique in this regard. So it'll just become a cat and mouse game of waiting for someone to find the unlock secret to each new series of drive.

And, if that doesn't work out perhaps we'll see something even more ingenious. I've often wondered if someone will totally reverse engineer PCBs for certain families to block/override certain functions. Imagine having a specially designed Grenada PCB that has the MCU hardwired to ignore the MC and sector re-allocation functions. No more shorting read channels, yada yada yada.

[data-medics]

Yeah, but I'm sure you agree that they've got their own backdoor into the terminal.

I've specifically had would-be customers of mine who's drives needed a firmware fix and were terminal locked, whom I've recommended to send their cases to Seagate data recovery. I'm waiting to hear back from a couple of them to see if they were able to do it.

I've lost cases due to this, which Seagate now gained. Monopoly here we come. In my opinion, it's no different than if Ford decided to put locks on hoods of their new cars and only give their service centers the key.

this is almost the exact thing John Deere do to their tractors/ farm machinery. There is a huge uprising as a tech needs to come out to do anything, and a scene exists with custom firmware and unlocked dash software. They say warranties will be void if others work on machinery even doing basic stuff as firmware "watches everything" and makes things expensive and take longer when JD techs arent available.

in regards to how it is done, there are ways that are not easy to figure out, and usually the methods are not reversed, but leaked from a friend of an employee or an employee that doesnt give a f###.

schemes like a certain value of resistor needed between two test points, jumpers, actual hardware that needs to be inbetween PC and drive (this is the case of burning firmware into some flash drive controllers)... will be very hard to stumble apon. I seriously doubt it is to stop home hackers as the engineers making firmware are so far removed from the internet "scene" and dev of new firmware is offset by years compared to what is available on the shelf. I dont think it would be to monopolise their DR centres as these would have to be running at a loss.

[Masterclass]

There's no any backdoor to get to SA.Only 2 ways:
1. Seagate authenication server
2. Patch hdd brains (far from being simple)

Authentication servers are horrible beasts. I hope it is better than Adobes corporate licensing clusterf****.
