The Solution for Seagate 7200.11 HDDs

Recommended Posts

The last cmd (m0,2,2,0,0,0,0,22) exited with 1 partition formatted. BUT! They are 2!

No :(.

Meaning that at the "level" it is very unlikely that the disk firmware knows anything about "partitions" (as defined in the partition table in the MBR).

I suspect that the "User partition" message you saw on the screen is not related to a partition like you are used to (software partition).

To the disk firmware there are two partitions, Firmware partition and User partition, or, if you prefer, "Reserved Area" and "User accessible area".

The partitions you make via software are inside the "User accessible area" or "User partition".

I wouldn't give any relevance to the message (in the sense that it seem to me like UNrelated to the actual issue).

The user, in fact, formatted it in 2 dynamic partitions. I made a full dd image and inspected it with recovery softwares.

Only the first one, 100GB is visible and I can recovery everything inside.

Dynamic partitions are "tricky" :ph34r: .

There are several ways how the user may have made them :

  1. simple volumes
  2. spanned volumes
  3. striped volumes
  4. mirrored volumes
  5. RAID-5 volumes

once set aside simple volumes (and probably the first partition you found is of such a type) and mirrored volumes, all the other types are VERY complex to recover and very few softwares can deal with them properly.

A tool known to be able to deal with those is File Scavenger (Commercial):

http://www.quetek.com/RAID.htm

The second partition is something like blank. Nothing inside. No file system, no files, nothing. Photorec doesn't find any files. Not even 1 small file.

Are actual sectors blank (00 filled)?

If yes, there is nothing you can do :(.

If no, there are maybe some possibilities :unsure:.

I can agree with u, but I saw many of these HDD giving me 2 or even 3 formatted partitions after the cmd m0,2,2,0,0,0,0,22 and they were according with the logical partitions they were divided. That is why I assumed they should be related.

How can I inspect the single sector? I didn't check them, just realized there is nothing to recover.

Anyway, I checked it with Seatools in windows (I will on DOS too in few hours) and it gives me an error while checking the internal diameter...

With *any* hex/disk editor.

The one I normally use and suggest is Tiny Hexer:

http://reboot.pro/8734/

Another very good tool (though not strictly a hex/disk editor) is dmde (which is IMHO an exceptionally good "advanced" recovery software):

http://softdm.com/

It does have "sector level" access:

Ok, is it the correct view? https://dl.dropbox.com/u/76462486/boh.jpg

If yes, all the sectors from this one (it should be the first of the problematic partition) are not blank, there is something written. Correct?

And if they are not blank. why nothing inside? :}

Yep, that is a view of LBA sector 202213012.

And if they are not blank. why nothing inside? :}

This is going to be a loong thread :ph34r: (and it does not belong here, this is becoming "generic data recovery" and NOT 7200.11 specific), please start a new thread for it.

Basically *any* software tries to interpret "RAW" data (which is stored in the HD sectors).

If even a teeny-tiny byte is "wrong" some software may be unable to interpret the data (just as an example removing/altering the 55AA Magic Bytes makes from the MBR *any* Windows built-in tool to fail interpreting a whole disk).

Recovery software tries to detect the sectors or bytes missing/altered/whatever and tries to correct them and/or hints you about where to manually correct them.

Most recovery software is aimed to "basic disks" and not to "dynamic disks" (thus they can find "nothing inside").

You need a dedicated tool AND a more than basic knowledge of the layout.

From the screenshot it seems like DMDE finds that partition allright, but you need to study and learn BOTH about how a Dynamic disk is made AND about the specific tool usage, we are well beyond the "click-here-and-I-will-automagically-recover-all-files-approach" a number of "end user" recovery tools tend to adopt.

Good to see you around :) and know everything is fine.

But don't be too proud about hard disk manufacturer change, though the 7200.11 (and to some extents the 7200.12) have been total crap, we do have the deskstar/deathstar preceding issue:

http://en.wikipedia.org/wiki/Hitachi_Deskstar

so I won't bet against the possibility that sooner or later another disk manufacturer will fall in a similar issue.

jaclaz

The real option is backup, and you also need to check backup time after time.

I went for WD not Hitachi. Looks like Samsung is also a good (cheap) alternative.

Btw, the Seagate list with FW problem is:

I got a lot more apart of how/what HDD companies works/do, and I can tell you is a total prehistoric business.

They should unite and create an UNIVERSAL and up-to-date standard for HDD's firmwares. Just the algorithm would continue to be unique, but the way to access the drive and allows us a much easier way to recovery, diagnostic, etc any HDD would hundred fold (or even more).

S.M.A.R.T. is way too limited and not completely reliable.

Is time to change, specially when many of us know the real future is indeed SSD drivers, when they fail you can still easily read all the stuff there, just cannot write/erase/format anymore. The same will never happen with HDDs.

I agree, but unfortunately now they are too small for storage.

Hi this is my first post in this forum. My friend gave me his PC with the following drive that has the same symptoms as listed in this forum.

Seagate Barracuda 7200.12 ST3750528AS

Would this be also included in this list? I want to know exactly before I start fooling around with it. Thanks!

Good. :)

Please answer this question:

Is in your view a

Seagate Barracuda 7200.12 ST3750528AS

a Seagate 7200.11?

If you answer NO, you posted on the WRONG thread as this is RESERVED to 7200.11 ONLY.

If you answer YES, you should see an optician ;) , as, besides missing the thread title and the difference between 1 and 2 you also missed reading the Read-me-first, where among other consideration is written:

If you have been pointed to this, it means that you failed to read here before posting there yet another time one of those SAME questions/problems.

The intended Target:

The scope of a thread about problems of Seagate 7200.11 drives is to try and solve two specific problems:

  1. BSY - or "busy" state
  2. LBA0 - or drive detected by BIOS with size 0

that are caused on a specific model (the 7200.11) by a specific firmware bug

....

The non-targets:

  • ANY other problem regarding this specific hard disk model (Seagate 7200.11)
  • ANY problem regarding ANY hard disk BUT this specific one (Seagate 7200.11)
  • ANYTHING NOT listed as "target"

and you have anyway posted on the WRONG thread :no: .

Please start a NEW thread for issues with the 7200.12 and/or search for posts about the 7200.12 which is NOT the 7200.11.

(there are DIFFERENT procedures - mostly UNknown/UNdocumented - for issues with the 7200.12)

Hi, I'd be grateful for any help that can be given!

I have a Seagate ST31000340AS with firmware SD81. I have been trying to apply the fix shown here but haven't succeeded.

I have got a USB cable connected to my drive and can connect via hyper terminal. When following the steps I have a similar problem to what AVIATEL was having on page 206 when trying the Z command:

F3 T>/2

F3 2>Z

LED:000000CE FAddr:00280575

LED:000000CE FAddr:00280575

I always get this error no matter how long I seem to leave between pressing ctrl + z and any other command. The motor pins are not touching - I have card in between.

Background info about the drive it constantly sounds like it is spinning up then down, once I hit Z this stops and I get the LED:000000CE FAddr:00280575 resposnce in the terminal.

Any suggestions on what to do or try now would be much appreciated!

I have managed to get one step further by removing all the screws:

F3 T>/2

F3 2>Z

Spin Down Complete

Elapsed Time 0.155 msecs

F3 2>U

once I send the U command I can hear that the drive is trying to spin up but seems to spin up and then down endlessly. The sound isn't a buzz but a whirring sound.

So again it sounds like the same problem as AVIATEL. He was recommended to read a few posts higher by Jaclaz - which post was this specifically?

I'm guessing I have a bigger problem than the standard bsy problem?

Thanks for the reply jaclaz.

I have tried this:

"Easy test, holding the drive in your hand, with NO power attached, then try slowly rotating it from a horizontal position to a vertical one and continue until you have completely flipped over the drive.

Power it up and try doing the same movements, you'll notice immediately (if it is spinning ) a kind of resistance due to the gyroscopic effect of the rotating platter(s)."

I can feel the drive spin up, then spin down, then spin up and down in an endless loop. What I can't feel or hear compared to a drive that I know works is the heads moving - no clicking, no feeling of them seeking at power up.

Any advice on what I can do or is it a case of send it away for data recovery?

It could be something completely UNrelated to the "main issue" described in this thread.

Is the disk LBA0 or BSY?

What I personally would do would be:

  1. clean the contacts (BOTH heads and motor one) THOROUGHFULLY
  2. try, following it to the letter, this guide:
    http://www.mapleleafmountain.com/seagatebrick.html
  3. try at first with the head contacts insulated, if it doesn't work, try again with the motor contacts insulated.
