The Solution for Seagate 7200.11 HDDs

Recommended Posts

Great job Gradius! :thumbup

And why did the guy above quote the entire fix?! Edit:LOL

BTW Maybe you should PM the moderator to ask if this topic could also be moved to the "sticky" section.

Dear Gradius,

You deserve my deepest regards and thanks for the help you posted here. It worked perfectly with no problem.

I joined this forum, only to thank you. I found this topic by google search engine. It is very simple and

perfect indeed. I would like, please, to exchange more information. I don´t know how to contact you in this

forum, I am new to this kind of mechanisms. It is always an honor to learn with

the "humble" professionals who believe in sharing knowledge.

Thank you very much,

My best regards,

Toni

Nice little module charlymex, never seen it before :thumbup

The only thing I can think of is wrong baud-rate, data-bits, parity and/or stop-bits :unsure:

Because you're using a rather unusual solution, you're practically on your own here.

Make sure you've got the settings right (and the driver installed correctly):

  • Speed: 38400 Baud
  • Databits: 8
  • Parity: None
  • Stop bits: 1
  • Flow control: None (but you can try "Hardware")

If that doesn't work, do a loopback test first by connecting the module's RX- to TX-pin.

Greetz,

Peter.

OMG... i got ANSI chars when i connect the HDD, i know i'm doing something wrong, but ... what???

If you are getting ANSI characters it's working. ;)

If you are getting GARBAGE characters (let alone if ANSI or ASCII :whistle:) it is NOT :(.

Usually the problem is missing, or ineffective GROUNDing.

Do a loopback test first, just to make sure the converter is working, then check that grounding the HD to BOTH the converter AND the power supply is effective.

Many thanks to all the folks on this site. I was able to repair my Seagate 500GB 7200.11 using the suggestions found here. I had gotton a BIOHD-2 error message and the drive would not boot. It did not even show up in the BIOS. I took it to the Geek Squad and was told it was damaged so bad that no data could be retreived from it. After running the commands on the hyperterminal I simply hooked it back up in the computer and it fired right up.

I quickly backed up all important data and started using the WD HDD I purchased to replace the Seagate pile of junk.

So, bottom line. This forum works.

Not a wise decision :(, if I may, you were lucky they didn't actually manage to ruin the thingy for real :ph34r: , according to the "standard" with which they are reported to operate usually.

Seagate Drive : ST3500620AS , Firmware : HP24

Location : Belgium

Problem : BSY

Original machine : HP

Succesfull recovery :thumbup

I used the solution described by AlexLillic on page 35 :

With a few small differences (only hardware) : all from RS website(international)

USB TTL cable & Torx screw drivers ordered from RS components (delivery in 2 days)

For the cable connection onto the Seagate drive I used the pins from an empty IC socket ,and soldered it onto a cable. Also used heatshrink tubing (just get a few sizes from your local electronics store to get the good size,else you need to order a whole box) as an isolator around the end of the IC foots,so they won't touch one another.

Thanks AlexLillic,Gradius and others ...

I'm looking forward to more goodies ,and you made me get the taste for datarecovery.

I still wonder where you got the actual list of commands for the controller board ?

Anyone knows were to get those (for seagate and other boards too)?

This might enable us to do this same stuff for other brands and models too.

Kind regards,

K.

You should have taken this cable: 687-7780

This one comes with a 8-pin header with 2mm spacing, so you would only have to cut it in half and

reseat the pins in the right order so you wouldn't need the IC-socket.

Anyway, I'm glad you were able to get it working again! :thumbup

I can't remember where I got this document from (I believe it was from some Russian source),

but it covers most (if not all) you'll ever need to know ;)

Greetz,

Peter.

I have an HP24 drive too that I recovered. Does anyone know if there are firmware updates for the HP and Dell drives? I don't think updating those with the SD1A is a good idea huh?

Excellent. This is the stuff I'm looking for ...

All that remains is to get broken harddisks to play with ...

And docs for Western Digital and other brands ...

Thanks Peter

I only recover the data - and get another drive.

You gotta be maschochistic if you're continuing to use the s***ty seagate drives ...

You got a new WD drive 500Gb for 50€ !

I would first try to diagnose the drive using SeaTools for DOS on your HP machine.

If it comes up with any errors, try to create an RMA at the HP-website for a swap

(since HP is the OEM supplier).

I guess you *could* try to update the drive with SD1A firmware (an ST3500620AS

stays an ST3500620AS, no matter who sold it), but you're on your own here , if you

decide to go that path. :unsure:

Whatever you do: first backup the drive before you do anything else! :yes:

Greetz,

Peter.

^^^thanks for the reply guys. Everything is backed up and all set. I'm just wondering if there is an update for the HP or Dell drives.

Most likely there is no update and if there was they wouldn't release it to the public right?

I tried to find a firmware update for the 7200.11 drives sold by HP when posting my

last reply, but couldn't find any mention of it on the HP site.

Your drive is most probably still under warranty, so you might want to swap it under RMA

at HP, after testing the drive with SeaTools for DOS.

If the drive is out of warranty and you're a bold person, you might want to do a normal

SD1A update from Seagate, but that's entirely on your own risk.

Greetz,

Peter.
