I've read everything. the disk responds to the point where I turn the power back on, then nothing happens. When I'm fast enough during the startup process, I can enter the command yet. Then happened but nothing more.

The given (now for the third time :realmad: ) guide is DIFFERENT form what you posted.
If you do the SAME things you posted, you will probably have SAME results.
Try the DIFFERENT approaches in the given guide:
http://www.mapleleaf...agatebrick.html

More explicitly, it says to try having the power disconnected for 60 (sixty) seconds, and NOT 15 (fifteen) as you posted AND ALSO says that some people had better success NEVER takng power out BUT simply changing level:

At this point, many say you need to disconnect the SATA power cable from the drive and wait one minute. Yes, count to sixty. Then plug the SATA power cable back into the drive. There is a bit of debate about this step in the forums but that is what I did and it worked fine in my case. *IF and only if* you choose not to disconnect drive power temporarily, you need to at least change back to the test level prompt (type F3 1>/T (enter)) at this point before continuing.

I tried everything I found on the forum and on the web. The left of you, the first entry was just an example that I have tried. But all to no avail. It all goes only up to the point where I have to turn on the power again. The adapter is fine, because I have successfully revived in the meantime another 2 HDD´s. I just noticed that the PCB is very very hot. But not matter, because I returned the HDD back to the customer. This allows the post to be closed.

It's good to be able to "close" this issue, but still, since one of the approaches suggested is to NEVER turn the power off during the procedure, it makes NO SENSE whatsoever that you are blocked when you power on again (you simply cannot "turn power on again" if you never switched it off).... :whistle:

OK, I got today the ordered cable. Let the HDDs total destruction begin ! :D Wish me luck. I hope the gizmo I ordered works and I don't do something stupid, like really bricking the HDDs.

OK, I installed the cable and driver, it is recognized by Windows now, but I run Windows 7 and don't have HyperTerminal. I downloaded it from Windows XP and (with the adapter cable plugged in, but nothing attached to the other side) I tried to type something to see if I get some response on screen, like I read somewhere. Nothing happened when I pressed buttons on my PC keyboard. I could see the red led on the cable adapter flashing each time I pressed a key, but nothing appeared on the HyperTerminal screen. Did I need to plug something (in my case the HDD) to the other end, in order to see if I get a response (test) from my cable adapter ? If so, does the HDD needs to be powered on ?

And another thing. The cable is a converter from USB. It added an USB Serial Port (COM10) to Device Manager. Port settings for this device are defaulted to 9600-8-N-1-N. Do I need this port to modify to 38400-8-N-1-N as well, like I do for HyperTerminal or should I leave those settings as they are ?

Still, I didn't try anything with my HDD on. I am trying to do this correctly and not miss some important step or do something incorrect.

My adapter bought is this model:

Thanks.

Phaenius, the idea of a read-me-first and of FGA's is to have them read FIRST, so that ALWAYS THE SAME questions are not asked anymore, since they are ALREADY answered (nothwistanding this this SAME questions have been asked OVER and OVER and OVER on this thread, and either answered directly or a pointer to the read-me-first or to the FGA's has been given):
http://www.msfn.org/...-read-me-first/
http://www.msfn.org/...-720011-drives/

If you had actually read them you would know how to perform a loopback test - which is what is advised BEFORE anything else to make sure that the adapter is not DOA and drivers, etc. are working.. (and - conversely - the utter futility of expecting anything with nothing connected to the adapter), besides point #8 of read-me-first and #4 of FGA's this info is not really hidden, and it is not very difficult to understand intuitively.
When you type "Hello" on the Hyperterminal, you are sending "Hello" on the Tx wire.
Since nothing is connected to it, your "Hello" gets lost in the atmosphere.
If you connect rtogether the TX and Rx cable, your "Hello" may echo back, returning to your hyperteminal through the Rx ..... :angel

Does the recommended guide here:
http://www.mapleleaf...agatebrick.html
tell anything about directly changing the COM port parameters?
Or does it tell you to ONLY change them in Hyperterminal? :whistle:

The idea of a guide/tutorial/read-me-first etc, is to try doing EXACTLY what is written in there WITHOUT any changes, modifications, etc.

Please do your homeworks, read the available resources, avoid asking AGAIN questions answered over and over, do not mix things "like I read somewhere"....

I do understand the idea of tutorials, but there are so many and cross-linked, I'll get lost. I will try and read as much as I can.

Thanks for the links.

Yep, but the idea (in order to simplify) is:
  • forget (temprarily) anything read anywhere else :w00t:
  • read the read-me-first
  • if you have questions, they are likely to be Frequntly Asked ones, thus probably you will find the answers in the FGA's
  • follow the recommended tutorial (and NOT anyone else)

The photos, screenshots and instructions that are on the lower part of that e-bay page are pretty comprehensive as far as the hook-up is concerned. All you have to do after that is to follow the steps as given in this thread. :yes:

The instructions in there are all OK :) but the idea is to avoid the risk of a newbie following anything else but what is known and re-known as "working" and avoid confusing him/her.

Before connecting the hard disk a loopback test is strongly suggested :yes: , and though the instructions seen on first post of this thread are essentially the same as in the guide by CaterinCanada (the now recommended guide) this latter is much more clear and complete (hence "recommended").

OK, sorry to nag again, this time I read the readme first and other posted links, I scratched my head and tried to put things together, but one thing is not clear. The final command is it:

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

like here http://www.mapleleaf...agatebrick.html

or is it

F3 T>m0,2,2,,,,,22

like here http://www.msfn.org/...ate-720011-hdds (first page of this thread) ?

Thanks again.

It's good to see how people actually listens to advice. :thumbup

If you are told to do EXACTLY what is in here:
http://www.mapleleaf...agatebrick.html
and NOT do anything else read anywhere else, HOW the heck you can have this doubt? :unsure: :w00t:

For the record, the commands are the same, if you omit the 0 (implicit 0) or if you type it (explicit 0).
Personally I find easier to count the 0's, omitting them is good to type it fast (which is completely UNneeded in this case as you should type slowly and double check and triple check everything before sending the command), the command is made of 8 (eight) comma separated values, if a value is omitted, it is parsed as if it was a 0 (zero).
Try quickly counting how many values are in this string:
m0,2,2,,,,,22
and how many in this one:
m0,2,2,0,0,0,0,22
:rolleyes:

I did. I checked the cable, performing a loopback, following the tutorial. It works like a charm, i get the response on the on-screen HyperTerminal. :thumbup

I didn't know that. For a person who never got involved in this type of things before, the two lines are pretty different. Good to know that are the same. I wouldn't want to give the wrong command, since it was a very important one. For other commands, I could recover somehow, but this last one is very important.

Despite all the :angrym: towards me, at least there's something you should like. I am taking a very careful approach to the whole procedure, asking around, risking some rotten eggs being thrown towards me.

OK, now I have all the information needed. LET THE UNBRICKING BEGIN ! (or the total destruction)

I got the torx, I got the working cable, I got the tutorial steps, only one minor thing I don't get. How on earth could I fry the board with my screws if I'm not careful ? I don't think I can do that even if I wanted to.

Wish me luck. Hope to be a http://www.pluslicen...sHappyBunny.jpg by the end of the day.

A bit of an update: I removed the PCB and looked at the contacts. They look pretty dirty, a wonder if you ask me how those metal endings make contact on the motor and heads. Do you recommend me cleaning or leave it as it ?

Don't worry :w00t: , even if it was impossible Murphy's Law would apply :ph34r: . (actually it is possible, rare, unprobable, but perfectly possible)

Well, reading the first post of this thread.

Yep :yes: , the one you were advised explicitly to (temporarily) forget about :whistle: in order to ONLY follow the CarterinCanada guide (in order to simplify and avoid doubts).

Jaclaz, a bit of a help pls. And please with sugar and cherry on top. I am stuck at one point. I did everything fine, but after I pulled the card and disconnected the HDD, when I reconnected the power, after I press CTRL-Z, I can't get to F3 T> It stays at F3 >1 What shall I do ? I am sure I did everything right so far. Everything went fine up until this point. Shall I close and re-open the terminal ?

OK, It seems my Hyperterminal froze when I disconnected power and reconnected. I had to close it and now it says it can't connect, since another program is using it ? What shall I do now ? Thanks.

Even further edit: I know I am annoying, but that is the least of my intentions. I read and applied the steps, but HyperTerminal freezing was not in it. I disconnected the cables, reconnected and now hyperterminal is responding. Shall I apply now the last command ? (m0,2,2,0,0,0,0,22) Now I am at F3 T> Again, thanks.

Last edit: IT WORKED ! :D I'm a happy bunny ! Hyperterminal froze after disconnected the SATA power and reconnected, I had to remove the cable from the computer and reinsert it, then apply the last command. Now, come to think of it, I don't know how on other people hyperterminal keeps connection after removing power and re-apply it. When HDD loses power, connection to hyperterminal shouldn't be lost ?

Anyway, thanks guys and especially jaclaz ! One HDD down, one more to go. :lol:

Good :).

Just in case ;):

Life is "trying things to see if they work".


You were a bit over-cautious, but I am happy to know that everything went well :thumbup .
Three notable differences between the "canonical way" and the setup you have are:
  • Windows 7 instead of XP or 2K
  • Using XP hyperterminal on Windows 7
  • USB to TTL instead of RS232 to TTL (hence the use of a driver to create a "virtual" COM port)
it is likely that the "disconnection issue" is related to the last one :unsure:.

Could be. I tried putty, but it's sooooo complicated, I didn't understand a thing. Windows XP hyperterminal did the job fine. At least there is something you could add to the tutorial. Some may get stuck to the point I have. In this case, they may try disconnecting the USB cable from computer, reinsert it and relaunch hyperterminal. Anyway, I don't know how many 7200.11's with this problem are there anymore. The model is quite old, I bought mine 4 years ago.

That's strange :unsure: , probably because most people (and instructions/tutorials about it) use it as a SSH terminal, but using it as a "pure" Serial Terminal is quite straightforward, or at least as straightforward as using Hyperterminal, just in case:

However, I'll post a sad bunny too, since after I plugged my unbricked discs to my computer, they are not working as intended and I don't know the problem. They are recognized at POST, they are recognized by Windows, the files are there, unaltered, but if I try to use the discs for some times, they just disappear from Windows, along with one DVD-writter, who suffers from the same problem. Could it be the power supply ? Could it be the motherboard ? Before my discs bricked, I had a Fortron 550 W power supply. Then my power supply exploded and I bought (didn't have enough money) a Corsair 430 W power supply. It's not a bad brand, it's 80% efficiency rated, it has PFC active, all-in-all, it's not a piece of junk. I measured the consumption and it gives me 200 W idle and 330 W full power (well inside the 430 W limit). What can it be ? I am a sad bunny again, until I find this problem too. Can MSFN offer support (on different section of the forum) on this issue either ?

Hi, I have a Seagate Barracuda 7200.11 (Model #: ST31000340AS, Firmware: SD1A) with the 0 LBA bug.

I have hooked up the HDD to my PC using the TX, RX, and GND terminals of a USB-TTL device that uses the Prolific PL2303HX chip. I believe it works and communicates as it should, as indicated by a TX/RX loopback test. The HDD is powered using another power supply (that is connected in a PC/to a motherboard), and I connect a SATA power cable from that power supply to the HDD, then switch on the power supply and press the "ON" button on the PC to power/spin up the drive.

The command "[Ctrl+z]" works as expected, as I am prompted with "F3 T>". The problem I am having is that the next command -- "m0,2,2,0,0,0,0,22 [Enter]" -- is taking forever to complete. It has been over 32 hours, and I have not received any prompt indicating the partition regeneration is complete. I am afraid to interrupt the process, since there are many warnings of people saying not to interrupt the partition regeneration process or risk data loss or an unrecoverable bricked HDD.

I read that jclaz instructed another user -- who was also waiting for 2+ hours for the same terminal command to complete -- to wait a little longer, then power off the drive and retry if not fixed. I just want to confirm if I should do the same. If so, should I first close the terminal window, then switch off the power supply, or vice versa (or does it not matter)?

Here is a screenshot of the terminal window that I have been seeing for the past 32 hours:

Can someone advise how I should proceed?

In your case you should wait another 12.42 ;) minutes, then re-do from start.
Seriously, there are three possibilities:
  • the actual command went through BUT (for *any* reason) there was not feedback of it's execution
  • the actual command went thorough BUT (for *any* reason) it was not actually executed
  • the actual command didn't go through (again for *any* reason) and thus wasn't executed
The same "remedy" applies to ALL three, after having waited a "reasonable" amount of time (that in this case means no more than 2 hours, i.e. double what was reported as longest time - which BTW I somehow believe to be a non-that-much-reliable report as the thingy should last at the most a few minutes, ten at the most), stop everything, check if the drive was unbricked, if not, start again from scratch.
To put it more bluntly :w00t: , the ONLY choice you have is to do the above.

There is no particular "order of operations" for the "shut down", to be on the safe side it is anyway "advised" to:
  • close terminal
  • switch PC off
  • switch "other" PSU off
then redo in the opposite order (as you already did correctly :thumbup ):
  • switch "other" PSU on
  • switch PC on
  • open hyperterminal
