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.

It's very clear that Seagate wants to prevent other people/DR firms from messing with their firmware and recovering data out of bad drives.

Terminal lock have nothing to do with stupid people trying to recover data. Stupid people will just open the drive outside a clean room even if the problem is firmware related. People with DR understanding will run terminal commands.

If Seagate wanted to prevent people from damaging drives with terminal commands they could just place some warnings or code the firmware in diferent way.

Or just change the ,22 key ...

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.

Seagate signed the firmware so Seagate have the key. Also they have the non-signed version of the firmware ... So ....

They can just use the original version without lock implemented and they are good to go.

If people already figured out "some " sollutions to gain terminal access on some drives then Seagate have the access for sure ...

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.

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****.

For repairing slow sectors use this command in terminal
m0,29,3,ffff,ffff,ffff,ffff,22
All data will be erased!!!

Great discussion! I must say we have not tried (Level T command m) 2b - Enable format seacos, enable reformat zone, enable log, enable certify, disable format, enable corrupt primary defects argument so far! We did "2d" :)

Locked terminal or even encrypted FW is used to comply with the FIPS Level 2 standard. Seagate is here to stay! Unless they don't cancel the entire diagnostic command port program development, Seagate drives will continue to use their way. This is why we made a simple AIR application (HDD Serial Commander). We translated commands to English and made command builder so one can play with it, run or export the command set to text file. Basic set of commands including Toshiba and Samsung is free to download. Even free version is a very useful tool for those who want to learn more about diagnostic command port. Mostly because its all in one place. If you like what we do you can contribute the project and download full version. Full version can also read/write FIDs (if it is enabled with the drive). Current goal is to finish "translation" of every single command including all their arguments (properties). I must also say over the past 11 months we discovered a great deal!

Full version is Public Beta 2.2.3 while current with our research group is 2.2.5 (Goal is 2.3.0 - all translated and verified :) ). May easily take another year :(

It is actually possible to create/run a batch file (script) and even store it to a drive. See Level 6 for more details (Seagate F3). This is also great "place" (level 6) for those who want to learn more about self-diagnostics.

Not to be confused since we had many questions related to Samsung, Toshiba or even WD (which is not currently supported). Full version will not have any more details nor commands for these drives. We currently work only on Seagate F3 series.

Thank you.

yes you are right
you must first unlock terminal
then use this command
