FINAL WARNING: Please do NOT try this if you have valuable data on your drive. Do not blame anyone if something goes wrong. You do it at your own risk. Remember that if something goes wrong, it is extremely unlikely that anyone will be able to help you remotely. One wrong command via terminal could easily result in a completely bricked HDD (I really do mean bricked = no one will be able to recover it, even Seagate).

Added by admin.


This tutorial is not for unexperienced users!!! Do NOT POWER OFF YOUR hdd,comp, during it, (EXCEPT IF I SAY SO)and you just to be shure connect your comp to UPS.

Great thanks goes to http://www.elektroda.pl/rtvforum/topic1198189.html who pointed me to
http://yura.projektas.lt/files/seagate/720011_ES2.html witch published commands from this motion picture http://www.elektroda.pl/rtvforum/topic1165039.html

This is my original link but i must edit it and enter complete information.
http://www.google.com/search?hl=hr&q=0+ ... ivanje&lr=
just enter in google 0 LBA

First you must have to build serial rs232 converter to TX,RX GND, you can use any data cabel from your cell phone,like i do, from siemens 35 series custom build data cable buid on this picture with max232. Be shure that you put zener diode 2V7 at the picture..Because you could burn your Tx,Rx, on HDD-s PCB.

So, when you build,get your adapter, connect it to this pins on Seagete drive.
[ '''''''''''''''| |''''''''' ] [ .. ..] ----> Rx .. Tx
You do not need to connect SERIAL-ATA CABEL
open hyper terminal or another type of terminal select Serial port example "COM1"
set bitrate to 38400bps
data bits 8
parity N
stop bits 1

it's default settings except bps.
plug power to disk and after that you will see on terminal something like this:

PART 1

Rst 0x10M
hit Ctrl + Z to get "prompt"
F3 T>

now, if your BIOS recognize disk but there is 0 LBA,0 capacity

all you need is to hit this command:

F3 T>m0,2,2,0,0,0,0,22 Enter

!!!IMPORTANT, dont turn hdd power off, or comp off, wait about 30 sec to 2 minutes until it finished!!!

then you see something like this.

Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8 Max retries Wr = 00, Max Rd retries = 00, Max T-ECC 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 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 User Partition Successful Format - Elapsed Time 0 mins 05 secs

After that hit

F3 T>/2
and
F3 2>Z
Spin Down Complete
Elapsed Time 3.038 msecs

Turn off power from your HDD, od shutdown your comp.


PART 2

If your HDD 7200.11 is not recognize by BIOS,

and after you connect him to COM1 and turn on power if you have this response for any command like:

Rst 0x10M
LED:000000CC FAddr:0025BF67
Ctrl + Z
F3 T>
LED:000000CC FAddr:0025BF67
your drive is bussy!

power off your Hdd
slightly unscrew one screw near to motor connection to PCB and put plastic visit card! or you can remove PCB.
Effect is the same..
power on your hdd,

Ctrl +Z

F3 T>/2
F3 2>
F3 2>Z

Spin Down Complete
Elapsed Time 0.138 msecs
F3 2>

now you put PCB back,or pull visitcard
enter this
F3 2>U
Spin Up Complete
Elapsed Time 7.242 secs
F3 2>

F3 T>/1
F3 1>N1
this is a S.M.A.R.T. erase

after that POWER off HDD, it means that you plug off power to hdd,
power on hdd,
reenter
CTRL+Z on terminal
F3 T>i4,1,22
this is G-list erase

after that POWER off HDD, it means that you plug off power to hdd,
reenter
CTRL+Z on terminal
F3 T>m0,2,2,0,0,0,0,22 Enter

!!!IMPORTANT, dont turn hdd power off, or comp off, wait about 30 sec to 2 minutes until it finished!!!

then you see something like this.

Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8 Max retries Wr = 00, Max Rd retries = 00, Max T-ECC 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 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 User Partition Successful Format - Elapsed Time 0 mins 05 secs

After that hit

F3 T>/2
and
F3 2>Z
Spin Down Complete
Elapsed Time 3.038 msecs

Turn off power from your HDD, od shutdown your comp.

And, i try i successfully recover 0 LBA on Sathurday,
here is a link who successfully recover BIOS recognition

Thanks to all! AND maysoft who let me repost original thread.
If you have any comment please say if it works.!

how many times is this going to be posted?

Useless info now that many recoveries are offering these cheap, and even free!!

Not worth the risk of further data loss IMHO

it look likes the disk have FW problems, but the client drop the disk to the floor.

Also the fw it looks like is the new one SD25 and not the SD15.

HI FRIENDS,

I HAVE A ST31000333AS. THE DRIVE IS NOT DETECTED BY BIOS. AFTER RECOVERING TWO OTHER DRIVES SUCCESSFULLY, THIS ONE GOES MORE DIFFICULT.

I AM GETTING THE RST 0x20M MESSAGE ALL THE TIME. ALSO THE MESSAGE LED:000000CE.....

IS ANYTHING CAN BE DONE?


TKS FOR YOUR ASSISTANCE.

TKS VERY MUCH
EPHRAIM

zebong, did you manage to solve the problem ?

I get one similar case but it is 1.5 TB.

Let me know if you have any luck.

meow, the fix posted above *should* work for you.

use at your own risk, as there can be complications which will result in even more difficult recovery, or worse, unrecoverable.


I recommend you send it to a pro as well.

No. I worked with ACElab PC3000 and there is no need to do such DIY solution.
Acelab support also told me it was hard to fix. Got to try harder.

Problem solved

Typically the problem is it shows "zero size" with disk ID detected. When you try to apply the "standard solution", it will hang and go to "LED:000000" error mode.
Now if you try the standard solution for "SG BSY not ready", it will not work either.
Same with "N1" command. It will just drop dead.
Check head after power on/off show that heads are ready.

Conclude that this is a firmware issue.

HELLO FRIENDS

IS THESE PROCEDURES APPLIES ALSO TO 7200.10 DRIVES.

PLS ADVICE

TKS
EPHRAIM

No i did make make this disk, and it was not FW Problem.

The client did not want to get the data, the fee was too hight for the client.

But the real Problem was HEADS, the disk has drop to the floor.

If you to listen to the disk, and try to understant what the disk tell-you.

Spildit, yes, this is one of the option but it did not solve my problem. My firmware revision is cc1g so it may be firmware specific.
