Posibila doar in tinerete, cand aveam timp, placere si rabdare
, acum sigur n-as mai fi in stare.Treaba e ca hard-urile Seagate de 500 GB in speta, din seria 7200.11 au un defect de fabricatie si necesita upgrade firmware (pentru cine le mai detine).
Altfel se poate intampla sa se brick-uiasca atunci cand ti-e lumea mai draga; pornesti PC si pauza, lipsa hard in BIOS, in Windows, etc.
Un nene al carui videoclip o sa-l postez mai jos mi-a deschis calea si astfel am reusit sa-i salvez lui cumnate-miu toata colectia de muzica stransa din 2005 pana in 2014.
1) TOATE modelele 7200.11 cu firmware SD15 au defect de fabricatie si sunt susceptibile la caramidat.
Seagate a recunoscut oficial si au pus la dispozitie un update de firmware pentru HDD.
...degeaba daca deja s-a stricat.
2) Singurele posibilitati pentru remediere sunt:
- Trimis la Seagate daca mai e-n garantie;
- Trimis la specialisti in HDD recovery;
- DYI.
O sa va prezint cea de-a treia metoda.
Am folosit-o cu succes.
Necesare:
- cablu de date NOKIA CA-42 (cel cu adaptor serial-usb inauntru).
- surubelnita TORX;
- carte de vizita plasticata sau echivalent.
Se desface electronica.
Se acopera alimentarea de comanda (se lasa doar motorul cuplat);
Se strange electronica, mai putin partea izolata.
Se instaleaza cablul.
Se taie cablul.
Se identifica TX, RX si GND.
Se conecteaza corespunzator pe pinii de resuscitare ai HDD (TX in RX si invers);
Se deschide Hyper Terminal si se acordeaza pe COM-ul cablului, cu 38400 baud rate si fara Flow Control.
Se dau comenzile de mai jos, EXACT cum sunt (inclusiv Case Sensitive; ganditi-va ca puteti nenoroci hard-ul iremediabil).
After a few seconds, Press CTRL+z. You should then see a prompt like this:
F3 T>
If not, you may have the TX & RX wires swapped. Switch them and try again.
Access Level 2 (type /2):
F3 T>/2 (enter)
F3 2>
Wait about 20 seconds, then spin down the motor:
F3 2>Z (enter)
Spin Down Complete
Elapsed Time 0.147 msecs
F3 2>
If you instead see a message similar to this:
LED: 000000CE FAddr: 00280D4D
Then you entered the commands too quickly after supplying power to the drive. Cycle power, wait 20 seconds,
then begin again.
Very carefully, remove the cardstock that you placed between the PCB and the drive head contacts.
Carefully replace and tighten the 3 loose screws. If you removed the screws, I suggest using a small
piece of masking tape to help you hold the screws while you put them back in place.
Then start the motor:
F3 2>U (enter)
Spin Up Complete
Elapsed Time 7.093 secs
F3 2>
Next go to Level 1 (type /1):
F3 2>/1 (enter)
And do a S.M.A.R.T. erase (create S.M.A.R.T. sector):
F3 1>N1 (enter)
When the prompt comes back up, turn off power to the hard drive, wait a few seconds, then turn it back on.
Wait about 20 seconds, then finally do partition regeneration:
F3 T>m0,2,2,0,0,0,0,22 (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 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
Do not turn off drive until you see this message.
Once seen, drive can be turned off.
Power down everything, place drive back into your computer, and confirm that it's working.
Acum HDD functioneaza ca si inainte, toata informatia intacta pe el.
Imediat i-am facut upgrade de firmware.
