If your drive is bricked, and you want to recover the data, here is a working procedure:
The Solution for 7200.11 Seagate HDDs:
Attention: This guide isn't intent for unexperienced users! Is very easy to KILL your HD if you don't follow the instructions with extreme caution. You have been warned! I'm NOT responsible for any damage or data loss it can causes.
You'll need:
- 1 (one) RS232 to TTL (I recommend those with +5V so you can use power from power supply PC).
- 1 (one) RS232 cable
- 1 (one) PC with Terminal software (like HyperTerminal) and RS232 port
- 4 (four) wires (for TX, RX, GND and +5V)
- Some jumpers, or similar (to link TX and RX on Seagate)
- Soldering Iron (optional)
- A fixed firmware from Seagate (to be released around 01/20)
- A torx tool
TX and RX connections from a SATA Seagate 3.5":
Connect TX and RX ports with RS232 to TLL adapter, you'll need something like jumpers in order to do that, or soldering directly to the PCB board. Connect GND and +5V to PC power supply, or similar.
Keep in mind RED wire from supply is +5V, and green or black are GNDs (yellow is +12V so don't use it).
Run HyperTerminal (or your favourite terminal software).
Config the RS232 port to: 38400 8 N 1
Fixing 0 LBA error:
To correct 0 LBA error, you'll need to do a quick format in order to regenerate the partition, just with m0,2,2 and the rest can be left blank by putting only commas or filling out with zeros. At the end you need to use a "ValidKey" code, or 22. So we'll have to enter:
F3 T>m0,2,2,0,0,0,0,22 (enter)
Now wait 15~30 seconds until something like this appears (it will vary a bit):
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 00, Max Certify Rewrite Retries = 0000
User Partition Format 5% complete, Zone 00, Pass 00, LBA 00008DED, ErrCode 00000080, Elapsed Time 0 mins 05 secs
User Partition Format Successful - Elapsed Time 0 mins 05 secs
ONLY after the message like above, enter:
F3 T>/2 (enter)
F3 2>Z (enter)
Spin Down Complete
Elapsed Time 0.147 msecs
NOW you can turn off everything.
Conglatulations, you done it! (Goodbye money! Oh my! I could be rich!)
Fixing BSY or CC errors aka BUSY (this will be kinda tough! I recommend a lot practice before to trying):
First you need to remove the PCB from HDA case, after that, connect RX & TX cables, verify that all is correct, and then power supply to PCB.
Explanation: To drives that hangs all the time in "busy" and on terminal (for example: LED: 000000CC FAddr: 0024A051 error codes), in which it blocks the terminal and it doesn't respond to any command, first we'll have to block off the time reading from plates on HD, in other words, power off your HD and DISCONNECT the PCB from HDA, with PCB alone, power up and press CTRL+Z (to enter on CMD mode), now we'll need to access the Level 2:
F3 T>/2 (enter)
F3 2>
And enter (to stop the spindle motor):
F3 2>Z (enter)
Spin Down Complete
Elapsed Time 0.147 msecs (the time will vary here)
F3 2>
Now the hard part. Pratice a lot without any power (of course), before even trying anything here.
Then mount the PCB back to HDA case, and DO NOT power off or disconnect the PCB from RX/TX (RS232) and power supply !
Now enter (to start the motor):
F3 2>U (enter)
You should get something like this:
Spin Up Complete
Elapsed Time 7.093 secs
F3 2>
Then go to Level 1 (by typing /1):
F3 T>/1 (enter)
Now lets do a S.M.A.R.T. erase (create S.M.A.R.T. sector):
F3 1>N1 (enter)
Now turn off (or power off) the drive. At this point I don't know yet if the drive power off alone after N1 command or not (I'm still need to order my RS232 to TTL adaptor). So, I'll just mention that as "Power OFF/ON" process.
G-List Erase (cert the reserved cyl):
F3 T>i4,1,22 (enter)
Power OFF/ON
Partition regeneration:
F3 T>m0,2,2,,,,,22 (enter)
You should get something like (in around 15~30 seconds):
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8
User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, ErrCode 00000080, Elapsed Time 0 mins 05 secs
User Partition Format Successful - Elapsed Time 0 mins 05 secs
If you didn't get the msg above, then you skipped something important, and turning off your drive now will render an unreadable drive, so be careful.
ONLY after the message like above, enter:
F3 T>/2 (enter)
F3 2>Z (enter)
Spin Down Complete
Elapsed Time 0.147 msecs
NOW you can turn off everything.
Conglatulations, you done it! (Goodbye money! Oh my! I could be rich!)
