The Solution for Seagate 7200.11 HDDs

Recommended Posts

When connecting power to your HDD via PSU, do you remove:

- GPU power

- 12v Rails power to motherboard

- Fan connectors

- etc.

So from your PSU do connect power to the HDD only?

Thanks!

I've been having problems trying to talk with my hard drive through terminal software. I've tried both PuTTY and HyperTerminal, but neither seem to work. I verified that my USB to UART adapater was working fine by doing a loopback test and it passed, but when I hook it up to the hard drive, nothing comes up when i push CTRL+z. Is it necessary to connect the ground cable from the board to the hard drive as well? Might have been my problem when I was trying it. I'm using this board btw http://alldav.com/index.php?main_page=prod...;products_id=21
You need connect GND too (pin3).

I think that the board is good.

I too am having having the same problem and pin 3 of the serial connector is TX Data. Why would one ground that pin to electrical ground of the power source??

ON HDD:

pin 1 (RX hdd) <--- TX Adapter

pin 2 (TX hdd) ---> RX Adapter

pin 3 (GND hdd) <---> GND Adapter

pin 4 (N.C. hdd)

So pin3 and 4 is where the jumper would go to limit the Seagate to SATA speed rather than SATA2 speed?? If so then one has to connector a jumper wire from the GND lead from the battery to pin3 on the jumper block??

Yes, you get out the jumper.

Well did that and the Seagate ST3500320AS which does not normally show up in BIOS, when I do a CTL+Z in Hypertoerminal which is configured for 38400,8,1,N,N I get no response from the hard drive at all.

I then revered the TX and RX on the adapter so that the TX goes to the TX on the hdd and RX on adapter to RX on the hdd. Was able to revive the hard drive and then flash it. Thanks for the help.

Hello everybody!

Thanks Gradius2 for putting vital info on resuscitating hard-drives, your contribution is very very precious!

I'm so excited: tomorrow I'll get the necessary gear and will fix my 30-days old "locked" 1TB drive plenty of data.

This condition makes my stomach burning... I think restoring access to personal data has no price...

At Seagate they say "mine it's not affected"... it's easy to act like this... they simply offer a drive replacement...

thanks so much

I'll let you know!

Update: haven't found the serial interface on shops, ordered on eBay and waiting for the postman to come, maybe this week I'll be on the job!

Hi,

Thanks for all the info but I am stuck with a problem. I have this Nokia CA-42 clone. There are 3 wires in it

Black, white and blue

Black is GND as it is mentioned on the IC. Also, i tested it through a Voltmeter and I am getting above 3.3V on both White and Blue, i.e., when connecting the Negative of Voltmeter to black and Positive to White or Blue

Then its saying connected to terminal, but i am not able to type anything in it. When trying different USB ports, i got it typing for a while but it was only momentary.

Now what to do ?

How to make it type in Terminal Window ??

Also i am not getting any random characters when i joined TX and RX or (TX + GND) or (RX + GND).

Now what to do ?

Hi Guys, I'm currently trying to repair my Seagate 1TB harddrive, and purchased a CA-42 cable off e-bay.

M/N: WACAS07

The cable when opened up has Red, Black, Green and White.

Has anyone else used this cable, the connectors are blue and the cable itself is black.

Just wondering which color is which.

Thanks Guys

I am so glad I found this forum. This evening I experienced the BSY error. IMHO I am competent enough to attempt this fix :whistle: , but I want to describe my problem to you guys before I try. Maybe if I am missing something you can warn me.

My drive is ST31000340AS bought last August.

Label claims it has the SD15 firmware.

The whole drive is encrypted using TrueCrypt.

There are three partitions.

The drive does not matter to me, I just want my data. Will the partitions and encryption cause complications for this recovery method?

One more issue. I experienced power failure this evening. On my first restart the computer worked fine for an hour and I shut down normally. On my next power up it failed and was not recognized in BIOS. I already tried the drive on my second computer and it was not recognized in BIOS. Still, my problem could be another issue not related to the BSY error.

I would appreciate any advice you could give me.

The black arrow is te character of the "ctrl+z" command.

It is due to loopback from TX to RX, a bad cable or the "echo" command of the hdd.

Can you see if your RX and TX wires are joined?

The answer is "no complications". This recovery method normally doesn't touch the "User Data" of the hdd.

This method repair the "Service Area" of the hdd, a hidden area of the aluminium plates. This area is out of the disk capacity.
