The Solution for Seagate 7200.11 HDDs

Obviusly, HDD don't work. BIOS recognize it, but not Windows.

Nothing so obvious.

If BIOS recognizes it, it is not anymore bricked.

The fact that you haven't seen the percentage of advance of the user format doesn't mean anything, the main part is:

User Partition Format Successful - Elapsed Time 0 mins 00 secs

To restate the obvious, this thread is about two problems:

  • 0 LBA
  • BSY state

Your drive is EITHER in one of the two states above (and then this thread may be of use) or it is NOT (and then you should start a new thread about your problem).

This:

BIOS recognize it, but not Windows.

tells us nothing in order to let us try and help you, we need DETAILS.

I'm trying to repair my hd using an USB to RS232. I have almost all clear, but there is one thing missing.

I have connected a USB to the +5v and the GND and then from the TX and RX to the RX and TX on the hard drive, but i don't know if i have to connect from the GND on the USB to RS232 to the GND on the HD. Is it neccessary? Or it's enough with the +5v extra?

Thanks a lot and good work!!

Wait a minute. :ph34r:

You don't want a USB to RS232, I repeated this info n times , but it seems like it simply does not pass through :whistle: .

The drive "speaks" TTL.

You can have:

(on a desktop or laptop that has a built-in RS-232 "serial" port):

  • a RS-232 to TTL interface

(on a desktop or laptop that only has USB ports):

EITHER:

  • a USB to TTL interface
    OR:
  • a USB to RS-232 interface AND a RS-232 to TTL interface

Ok jaclaz, thanks for your answer.

BIOS recognize it (last week didn't), and then one of three things can happen

  1. I get a black screen in windows startup
  2. It take minutes to startup, and when i open "my computer", disk is there but don't show his size. When i click on it, i get a Windows message "I/O device error".
  3. Same as number 2, but with the popup of "new hardware found ST3500320AS but with the same result

Thanks for your help jaclaz, i have been looking for info and the interface is USB to TTL, but has written something about RS-232...

Anyway, the TTL, has 6 conections: 3.3v, RST, TXD, RXD, GND and 5v.

I connected:

- TXD AND RXD to RXD and TXD on the HD.

- GND and 5V to an USB cable for power supply.

Now the question is: Do I have to plug the "GND on TTL" to "GND on HD"? Are all steps i made right?

Thanks a lot!!

Yes, grounding is a must, expecially if you are drawing power from two different power supplies, but I wonder if you are using one of those auto-adjusting TTL interfaces :ph34r: , see here:

it is possible that if you supply 5V to the interface you get the "wrong" TTL levels in output.

So, you should start a new thread about your current problem, drive is not anymore bricked and it doesn't "belong here" anymore.

The thing you are missing is that a drive that has bricked is a FAULTY drive, the methods we use on this thread may unbrick it, BUT there is no magic wand, after the unbricking the drive is to be considered FAULTY, you should get all the data from it, if you can, and then eithr throw it in the dust bin or use it as tertiary backup media.

It is possible that besides the bricking problem your drive suffers from other problems you should run the Seagate Diagnostic Tools on it and report (again in ANOTHER thread).

Hello again.

Here is how i managed it: http://yfrog.com/5cesquemagj

The usb gives 3,3 v, but i read that it must be connected to the 5v on TTL, but i can put it on 3,3 v if you think it's better. Is it connected in the right way?

I don't know if the TTL is auto-adjusting, you can see how it is at the picture attached. Maybe you will know it....

TTL gives power to HDD through TX? I can use a Polymeter to check the output...

Thanks, thanks, thanks!!!

Now, it is NOT about level of power going in, it's about TTL voltage level getting out.

Read the post I linked you to.

Read the link in it:

http://www.interfacebus.com/voltage_threshold.html

Check the specs of your interface, connect it wisely. ;)

I personally doubt that on a USB to TTL interface the good engineers who made it wrote "USB to RS232", but of course everything is possible. :unsure:

Where did you buy it?

Are the specs of that interface available online?

You're right. With an ubuntu live cd, i finally got access to the hdd.

Thanks again!

I bought that on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250399285596&ssPageName=ADME:B:EF:US:1123

The specs on the ad:

USB TO TTL Converter Module

Description:

# Built-in USB to RS232 Transfer chip.

# Designed to be used for USB to TTL electronic projects.

# TTL interface output, easy to connect to your MCU.

# Power LED.

# Dual 3.3V and 5V Power output, work with 3.3v and 5v target device.

# Compact design.

# Dimension: 41 mm x 15 mm

It has 3.3v and 5v power output, i think that if i connect the usb to 3.3v it will give 3.3v out and if i connect usb to 5v it will get 5v out, doesn't it?

I don't know very much about this so i appreciate help very much!!

Would it be better to connect the USB to 3.3v?

Thanks, thanks, thanks!

I start to think that it is a different inteface, does it have a CP 2102 chip? :unsure:

https://www.silabs.com/Support%20Documents/TechnicalDocs/cp2102.pdf

It should be similar in concept to this one:

http://www.sparkfun.com/commerce/product_info.php?products_id=8531

It has to be checked if the one you have is configured to be powered from the USB bus (and you can DRAW power OUT of the +5V or +3.3V lines ) or if it is a "passive" interface and needs to INPUT power FROM either the +5V or the +3.3V.

It should be similar to this, and powered from the USB connector:

http://www.pololu.com/catalog/product/391

if you WITHOUT ANY CABLE connected to it, attach it to a USB port you should be able with a multimeter to read 5 V between +5V and Ground and 3.3V between +3.3V and Ground

EDIT:

Affirmative, I reviewed the thingy, it is powered from the USB connector:

# Dual 3.3V and 5V Power output, work with 3.3v and 5v target device.

Thus, you need to connect to it ONLY three cables:

  1. Tx on board ->Rx on hard disk
  2. Rx on board ->Tx on hard disk
  3. GND on board ->GND on hard disk

Please note that if you have problems like "random characters" in Hyperterminal, GND should also be connected to any of the GND cables coming from the power supply which is powering the HD.

I confirm what you thought, it's powered from the usb.

Since my 2/25/2010 post, I've scoured about and seen a few comments noting terminal responses of "small arrows" but none (so far) of the "beta character" I received in response to the N1 (S.M.A.R.T. erase & creation of S.M.A.R.T. sector).

Does anyone have any information on these responses to terminal commands or recommendations of additional places to research?

Note that these are received from a properly connected HDD (connections were not changed between expected responses and these 'odd' responses). My 2/25/2010 post displays the overall terminal session with a screenshot in the case of the beta character since the overall session translated it to an accented a character.

At this point I am contemplating an attempt to hook the drive back up via USB to assess if it is noted in BIOS, though I doubt it would be based on the small arrow response to the CTRL-Z terminal command. I have refrained from further terminal commands or operation in hopes I could find additional information on beta character responses to the N1 command and the small arrow response. So, at this point additional input would be most appreciated. Thanks.

Well you can do one of two or both.

1. Go through the process again hopefully this time, not getting any weird Greek letters.

2. Go ahead and plug it into the computer to see if it is recognized.

At this point, I do not see any of these 2 approaches as damaging your hdd, IMHO. I'd personally go for #1 just to make sure that everything worked properly.

Hello

i'm new of this forum.

I'm italian graphic designer and i have three years of my work on a seagate barracuda 7200.11 (st3500820as - firmware sd25).

The hard disk in block and return I/O error and error 1117 error.

This guide is for me? Can i recover my data?

Thans a lot.

ps. the hd make a little click sound and sometimes the pc seen it as 0 gb and somethimes 2 TB.

Thanks, thanks, thanks!!

I have already fixed my HD, thanks to all of you, specially JACLAZ!!

One last question, this solution works for all kind of Seagate HD's with firmware SD15??

Thanks again!!

Thanks Jaclaz!
