I read to send the M0,2,2,,,,,22 cmd before N1 in this case to solve the problem.

Hello, I have a fu**ing Seagate ST3750630AS HP26. With Seatools for DOS I saw "Max Native Address 0", but it shows the right LBA capacity 750GB. Since it is impossible to use the drive, how it is possible to change the wrong value from 0 to the correct one? I tried MHDD with NHPA command, but it stucks without output. Thanks for any idea.

I really don't know what he did, really. I just have a burned PCB and it was not. I will let you know if he confirms me the work. Thank you

Hello, I have another problem with this never ending problems hard drive. To make it shorter: my client have a 7200.11 in busy state, he sent it for a recovery in a specialized society. They asked 1.200 euro (tax included, lol) to recover everything. My client said no and asked the hard drive back. When the hard drive returned it doesn't spin up again. Now, it is my turn, he gave it to me. He described the initial problem and I am pretty sure it was a busy state. I checked the PCB and there is a burned chip (not the diode unfortunately). What to do? Do you think that buying a new compatible PCB, swap the eprom chip from the original PCB onto the new PCB and then unlock it as usual will solve the problem? Obviously I have doubt this society changed the original PCB with a broken one, but I can't check it...........................

Your USB-to-TTL adapter is apparently one of the few USB-adapters which works at the correct 3.3 V level (and _not_ 5 V). Could you tell us what's the make of the USB-to-TTL adapter, chip No, looks or brand name? my PL2303 has the possibility to switch +3,3V or +5V and it works like a sharm. You just need to set up a jumper.

try with testdisk under linux. I am worried for the first wrong try

cross posting is really bad

does the motor spin up correctly? If yes, it can be lot of things: bad adapter, wrong cabling, wrong settings of the adapter, wrong ground and so on....

Hi, it was a 500GB ST3500820AS with SD15 firmware (now SD1A). I did tons of them, never got back such reply from the HD. I did all the steps as in the first page.

I want to share with you all a "strange" output from the last hard drive I fixed (10 mins ago): F3 T>m0,2,2,,,,,22 Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8 User Partition Format Successful - Elapsed Time 0 mins 00 secs There is something missing (eg, from the first page: User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, ErrCode 00000080, Elapsed Time 0 mins 05 secs), but it is seen by the Bios and it works, all the data are inside as it was supposed to be. What do you think? Just for curiosity...

Thank you very much, I want to ask you something else, just a try: the F,,22 cmd worth a try in both my situations? What do u think? How to send it? I mean, just a ctrl+z to access the console and then send F,,22 cmd or something else before and/or after? Thank you.

Hi all, I have fixed many hard drives, 99% of them without a problem, everything was smooth and flawless. First of all: I want to confirm what Chrissygoe said: I had a hard drive spinning up and down in loop. Nothing on the Bios. I did the fix as it is in the first page, when I sent the last command (m0 2,2,,,,,22) the motor spinned down and the hard drive didn't send anything to the TTL. I left it for some minutes, I guess more than 10 minutes, but it spinned up again and it sent the correct output. Now it works perfectly. Returning to that 1% of my insuccess: 1) a hard drive didn't send the output after the m0 2,2,,,,,22 command. I waited several hours. It was an HP12 firmware, but it was recognized by the bios after the partial fix. I tried with a firmware update, I was able to upload the official HP13. I tried again the m0 2,2,,,,,22 command. No output again. The hard drive is seen in the Bios (with SMART errors), but no data inside. 2) another hard drive was fixed till the end, correct final output. The bios sees it, but very slow. No data inside. Any idea? I tried with recovery softwares without success. Thank you P.S. anything about the spin up error after /U cmd? The motor seems to work properly.

I read it too fast, I am not native English speaker and I make silly mistakes time to time The IDEA was not for a single hard drive of mine, I have a rather good system to back up my data, but for my clients. I am having more and more people asking me to recover their data. I was exploring the idea to improve my possibilities to recover. Thank you for your support. To me it seems it is possible only to swap heads and pray God the surface is not too damaged.

of course it is not to resell the drive. It is for data restoration. Anyway, thank you for your reply

I am not asking what I need to make it possible, I am asking if doing it the drive that will receive the platters from the donor will read the data inside.

Hello everybody, If a hard drive has serious problems with heads or with the motor and, obviously, it is not possible to access the data, a swap of the internal disks in another drive, same model and firmware, can make the data accessible? I can make a glove box to manage with them to prevent dust. Thank you.
