If using Windows, have you initialised the drive in Disk Management?

BTW, it would have been better to have started your own thread.

I have a strong desire to Engineer a tool, for all of us, to incorporate firmware access/recovery for these hard drives as I see it pointless to "rent-a-hdd" when it suddenly crashes on you and you're faced with recovery fees just to have another one crash on you... so on..

thus far I..

designed my own RS-232 to TTL solution shown here (nvm magicHack) .

The chip you see is the serial Firmware chip, awaiting r.E. (RevEng[e]) from me. This is pretty straight forward, functional and is getting me closer to retrieving over 2+T of software on my backup drive!

This is the actual controller board. Luckily, SeaGal engineered it to "stand-alone" without any dampers or pullup/downs in circuit so this was possible without destruct.

Eventually while intercepting the SATA protocol I'll closely study the firmware, memory stack and commands from the MCU (tips welcomed guys) . Have a look:

Their debugger equipped bootstrap code is called "Yeti Boot", dating back to 2007! seemingly beautiful flexible code for the Barracuda ST31000528AS stuff and others but like I told the Seagalte crew "I just want my data back, you didn't have to start a war.."

The HDD TTL access - You should have a dongle with a connector that will fit a 2mm pitch, 4 node connector (Ex: IDE notebook drive). Connectors are labeled: [ TX|RX|GND|N/C ], hard drive writing faced up or just remember "TRiG" and go with the Max232 family & follow the datasheets.. enjoy; interceptors circuits are next. ~UART "I don't believe in luck; I believe in Precision."

Yeah, won't you believe it?? :lol: however It's pretty straight-forward. Can't get a hold of a manual so we'll just create our own.

The MCU has 10+I/O ports DAC/ADC interface?? with most likely a JTAG or similar interface which may be enabled during this stage... I'll find out if so.

It shouldn't be all that hard. I know our .ru friends been at it diligently, making progress but I'll post my stuff, schematics, datasheets etc for the time being for now here's the Schematic to my RS-232 to TTL Dongle:
