Opening drive wasn't a smart move.
Seagate and Maxtor drives were notorious for their LBA and BSY errors. I don't know what model you have but I had something similar few years back. I'll copy/paste little tutorial I posted on another forum. Since you don't have much to lose now, it's worth while to go try to fix your drive.
What I did was this;
For folx among us who are stuck with dead hard disk, this is probably the only option to save data and lot of money in case you had something valuable on your drive.
So, what is the 0 LBA and BSY error? Well, 0 LBA error happens when your BIOS won't recognize your HDD at POST and sees your disk as an 0MB drive.
BSY error is when your HDD enter a halt state, or BuSY state. When this happens, your drive won't be recognized by BIOS at POST moment because your SATA port is locked up.
So.. What now?
You'll need the will and courage to go trough few steps that sound more complicated then they are. Still you'll need to focus on what you're doing because it is easy to make mistake.
What do we need?
First, we'll need computer with terminal software like HyperTerminal or Realterm.. If you use Win.XP, it's already there. I'll get to this later.
Next, one TTL adapter I'm using Phox.de for Siemens C/S/M-35/SL45 because I already had one at home, but you can also use Nokia CA-42 or DKU-5 Cable.
It cost only few bucks and saves you trouble of adding extra power supply if you would use RS232 to TTL adapter for example..
Now we have to find out what are the RX, TX and ground connections on CA-42. You'll have to solder and isolate connectors to hook up the drive to adapter. I'm handy with electronica so I used connectors from one old ATA HD cable. Those fit perfectly and won't flop out in middle of operation.
Now you'll need to configure HyperTerminal.
Open Hyperterminal,and choose the COM port that your cable is using. If you are unsure of which COM port to use, check your device manager (look in the "ports" sub-section) to see which COM port your cable is using.
In Port Settings fill this values:
Bits per second : 38400
Data bits : 8
Parity : None
Stop bits : 1
Row control : None
When this is done, go play with terminal software to find out if everything works as it should.
Short RX and TX pin of your adapter to see if you can type anything in terminal software. If so, you are ready to go, but before that you need to remove the Printed Circuit Board from HDD case and isolate PCB circuit board with piece of paper between PCB and hard drive where the other connector is, but leave the motor contacts connected. Fasten PCB with two screws next to motor connector.
Now you need to hook up the dead drive to CA-42 adapter connections you just made.
From PC (TX) to -> HD RX
From PC (RX) to -> HD TX
Ground connection to HD
If your system cannot talk with HDD switch Tx with Rx lines.
If everything works, plug the SATA power cable into the drive, and wait until drive motor stops.

Type CTRL+Z and you should see a prompt like this F3 T>
F3 T> Type /2 and press (enter). It should say F3 2>
F3 2> Type Z (enter)
Now you'll see something like that;
Spin Down Complete
Elapsed Time 0.137 msecs (the time won't be same as here)F3 2>
Now carefull remove piece of paper with drive still powered by SATA power cable and TX/RX lies connected.
Carefully screw PCB board back on HDD case. (make sure that the screws don't short the PCB board)
To start the motor, type U
F3 2>U (enter)
Now it should look something like this:
Spin Up Complete
Elapsed Time 7.129secs
To go to Level 1 type /1 and hit enter
Create S.M.A.R.T. sector
Type N1 (enter)
IMPORTANT Power off the drive, wait 10 seconds and now Power ON your drive.
Press CTRL+Z on terminal and type:(case sensitive!!!!)
F3 T>m0,2,2,,,,,22 (enter)
After 15-30 seconds, you should see something like:
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8
User Partition Format 6% 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
And should bring you back to the F3 T> Prompt.
Now you can unplug everything, turn off computer and re-install your drive.. Should be working fine now..
Update your drive with the latest firmware as soon as possible.
If there seem to be interest to this topic,I will post some pics to simplify things a little.
If you wish to use original XP HyperTerminal on Win 7 machine, you need to copy hypertrm.dll and hypertrm.exe from XP computer. To find hypertrm.exe go to C:\Program Files\Windows NT and hypertrm.dll in C:\Windows\System32.
You can park them in any directory, but to do it neatly I put it in Communications folder where it should be.
You can use Realterm instead if you wish.. Great little program http://realterm.sourceforge.net/
Hope this will help you..
Down in the bayou, Bubba called an attorney and asked, "Is it true they're suin' the cigarette companies for causing people to get cancer?
"Sure is Bubba. But why you asking?"
"Cause what I want to know is, I was thinking, can I sue Budweiser for all them ugly women I've slept with?"
