Hi there guys

I have a problem with a Seagate drive purchased in 2007

Recently the drive was making a harsh bleeping sound but it was not clicking

Firstly the drive would detect in bios but not in windows, as windows would not power up as it did not detect the drive at first the sata cable from the drive to the motherboard was replaced as there was a crease in the cable but no joy.

The same bleeping noise would be made once power was connected as it would 'spin'

To avoid damage to the motherboard, disconnected the drive off the motherboard connected the drive to the pc via sata-usb dongle. Hardware manager detected a usb external storage drive but unable to access the data from the drive from within windows tho 'My Computer' would hang and then freeze when trying to access the data.

After a reboot left the drive to run in the background for a good 30mins and the bleeping became quite constant but still unable to access within windows.
After a final attempt there was a little smoke coming form the power connector with a distinctive smell, there is no physical damage or any components that have burnt out but it's fair to say that there has been some form of physical damage as the drive no longer spins and a distinctive smell of electrical burning can be smelt as soon as power is connected to the drive.

Can the data be retrievable if the pcb was replaced ???

cheers for your help

Looks like you have two independent problems. First: spindel seized ( consider sounds and predisposition of this drives), second: pcb electric failure.

In any case ,data could be retrievable even we don't have original PCB. But price will be high for sure.

Ditto.

Now it all depends on how much is your data valuable.
Go to a pro so you can at least get a proper quote.

:'(

So your data is not so valuable right?

You can possibly repair your board at no cost, if the problem is only a shorted TVS diode.

Otherwise you can purchase a PCB for US$40 plus $10 for a "ROM" transfer:

The TVS diodes are the two black components to the left and below the mounting screw in the top right corner of this photo:

That said, this will still leave you with the original fault.

The drive would not try to spin if there was a shorted TVS, right?

TVS solutions are helpful in specific cases, but it is not a "one size fits all" for data recovery . . .

I would try to replace PCB and move ROM.

This is the spec of the hd in question which im having trouble with

Technical spec

Seagate Barracuda 7200.9
ST3400633AS
Part No:- 9BD145-304
F/Ware : 3.AAH
Site Code:- TK
PCB :- 100355570

Here is a pic of the pcb

cheers for your help guys

You need to check the resistance of the two components in the attached photo clip.

What readings should i be getting ??

The TVS diodes usually fail by going short circuit. If either measures close to 0 ohms, then it is shorted. Otherwise its resistance will depend on whatever else is connected to the same supply.

Hi guys how to i do about moving the ROM ???

I believe the "ROM" is the 8-pin serial flash memory chip in the top right corner of your photo. It should have a "25" in its part number.

Your board supplier should be able to transfer it, or its contents, to your donor PCB. Otherwise, if you are unable to do your own soldering, then ask your local TV repair shop to do it for you.
