Seagate Momentus 5400.6 ST9500325AS Bad sectors

[techameed]

Hi
I have few USB Portable Disks from Seagate ("Freeagent Go") which are not getting detected in the Windows.

So I opened the portable device and took out the seagate hard disk from it.
Details of the Disk are ->
Seagate Momentus 5400.6
Firmware 0002BSM1
Model ST9500325AS
Interface = SATA

Now I tried to connect the disk direct to the PC. But BIOS is not detecting the disk. So I did following activities
1) Connect RX TX pins to RS232 connectors
2) Executed Following terminal commands (just for check), But i got stuck with Init SMART FAIL error.

Spin Up Complete
Elapsed Time 3.624 secs
F3 2>/1
F3 1>N1
Init SMART Fail


3. Now I tried again with direct following Terminal commands

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


This time command was successfully executed , with no error. :w00t:

4. Now I connected this hard drive to the machine, and now this Hard disk is getting Detected in the BIOS.

5. But when i start the Windows - It automatically start the "scandisk" operation on the newly detected Partition (I am now desperately waiting to finish this scandisk operation, so that i can get my data back... but) :}

6. Scandisk Operations - shows me continues Unreadable Sectors , so i restarted the systems and on the next scandisk interaction with the this hard drive was skipped, so that i will be able to diagnose the disk with some other tools like HDD Regenerator

7. HDD Regenerator shows me NON-REPAIRABLE bad sectors.

8. I tried the same thing with one more same momentus drive (everything same as specified above)- but to my surprise I now found Repairable Bad Sectors but the count was tooooooo high. In 48hours HDD Regenerator have fixed only 9GB out of 500GB disk. So I dont have any other chance to Stop this activity as well.


Now I tried to explain the problem in as maximum details as i can provide.
So please help me out to fix this drives.

I do have few more momentus drives in my friend circle, and all are having hopes associated me. :wacko:

Please do help me out.

Who gave you the idea about the commands you used ?

sorry for 2 consecutive posts the previous was incomplete due to connection problems :

...continue...

... seems that either you got a suggestion or took the initiative by reading "stuff" on the internet.
Facts and consequences :
1) drive not being detected is a consequence of "something" , the cause can be multiple with same symptom.
2) SMART INIT FAILURE should have been a loud alarm...
3) Why go on with m0 command ? The fact it ended regularly didn't mean the problem was solved, in fact...
4) ... data was still not correctly accessible (no wonder as the problem was elsewhere right from the start, correct diagnose missing).
5) You'll soon discover that data after scandisk and "regeneration" (?) will be missing or badly garbled.
6) On the other drives, if the procedure was the same without a diagnose, the "regeneration" (?) will not work as the problem (due to the symptom) is another.
7) Little question : do you know what exactly m0 command does ?

And last but not least... were the drives to be REUSED or did you need data from them ?
