Tutorial: resolve 0 LBA,SEAGATE 7200.11 BIOS don't recognize

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
