Unlocking Terminal of Seagate es2

by Tuesday, February 07, 2012 0 comments




Here's what I discovered after many attempts in the last few nights.

Terminal of my 2 ES.2 drives was locked (drives were in BSY state) - every 3-4 seconds I received from their terminal message LED: 000000CC....

Standard solution which is widely known for 7200.11 series (ST******AS) doesn't work for locked ES.2 series (ST******NS) !!!

But i've found a way to unlock terminal of my ES.2 drives :) what allows then to repair hd in a standard way (solution from Yura/Okzo).

1. Disk has to be complete (PCB+rest together), NO isolation between the PCB and the rest
2. In the terminal you will see every few seconds message LED: 000000CC ...
3. between these messages you can unlock the terminal by pushing CTRL+Z. It will show a line: "F3 T>" and it will be Unlocked for about 1 second
4. During that 1 second when you see "F3 T>" message but before you receive next "LED:000000CC..." you must short two points shown in the following image (they are known as "read-channel").





You must hold them short about 20-30 or little more seconds.
If you won't see next "LED:000000CC..." and disk will issue few unpleasant sounds then after some time you'll see in the terminal message "Input Command Eror".
Now the disk's terminal is unlocked!
Still holding those 2 pins short issue command /2 and then Z (they're cAsE sEnSiTiVe!).
When disk's engine will stop you will see message "Spin Down Complete" and now you can release the short between 2 pins.

Next do repair with standard instruction (as for 7200.11) - all below is cAsE sEnSiTiVe!:
F3 2>U
Spin Up Complete
F3 T3>/1
F3 1>N1
F3 1>/
F3 T>m0,2,2,0,0,0,0,22
and wait until you'll get message
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 00, Max Certify Rewrite Retries = 0000
.....
User Partition Format Successful - Elapsed Time 0 mins 05 secs

Good example (also extended) gave aviko, in post number 529 in topic # 128807
It is at: http://www.msfn.org/board/index.php?showto...mp;#entry832876

I am a complete amateur (not DR professional), and of course, give no warranty for the described procedure.
It worked for me and my two ES.2 drives are alive now.
Of course, this procedure or the incorrect use might as well burn your disks and data.
I don't assume responsibility for such cases - everything you do at your own risk.

This procedure of ES.2' terminal unlocking is my own discovery, and I'd like to share this knowledge with other poor owners of bricked (in BSY state) ES.2 disks.
