3) Prepare the hard drive
Do not remove the circuit board from the hard drive, attach all screws.
Attach the adapter to the serial port on the drive as shown in the picture.
Connect your independent power supply to the drive. Do NOT turn it on yet. (The SATA power cable is the wider connector, the data cable is the narrrow connector)
4) Get HyperTerminal or PuTTY ready, but don't open the connection yet.
5) Turn on the power to the drive, and connect the adapter to the USB port on the computer.
6) Do the follow in HyperTerminal (keys (case sensitive) you should actually press are in red, things you should see on screen are in blue. Everything else is just additional comments)
Press Ctrl + z, you should get this prompt:
If not, please check if HyperTerminal / PuTTY are set up correctly. If still no prompt, try isolating the board from the drive, and follow the instructions for 7200.11 drives instead.
F3 T>/1 (enter)
Erase the S.M.A.R.T. data by typing "N1". This does NOT affect the user data.
F3 1>N1 (enter)
(wait for a while)
Restart the drive, then hit ctrl+Z as before.
Now we have to format the user partitions. Despite its name, this step does NOT format the user data.
F3 T> m0,2,2,0,0,0,0,22 (enter)
(wait for a very long time, up to a few minutes)
User Partition Format Successful - Elapsed Time 3 mins 10 secs
Turn off the drive, disconnect the serial adapter, reconnect the SATA data cable (narrower cable) to the drive.
Turn on the drive. If everything went well, the drive should be visible. Backup your data IMMEDIATELY!
