Specs: Windows Vista
My harddrive stopped spinning, it seems that I have blown up the drive by using the wrong power. I am looking for the same drive to exchange the electronic on it and see if that helps making my drive alive again.
Who can help me? Please

Ebay may be the way to go, a simple search for "HDS725050KLAT80" gives 15 current results ranging from $1 and up. If your lucky you might even find one locally to save on postage.......

If you are determined to try I would suggest checking that all of the connections are easy to reconnect without any excessive soldering before even looking to purchase a replacement for parts.

There is no guarantee that it will work even if you do connect a new/replacement circuit board.

Thanks, but I am rather desperate, so I have to try anything!

Did you apply 115VAC to the computer? I assume your local voltage is 230VAC?

If you did that you may have damaged more than just the hard drive.

Are you sure the power supply is working correctly now?

If possible, test the hard drive by connecting it to a different compatible computer.

No, not 115VCA, but I did connect a wrong adapter to it.
Actually I crossed two drives/adapters and both went dead.
But this Hitachi is the most important one.
I tried the drive in another housing and that seems all to be ok, accept that the drive does not spin. So it must be the circuits on the drive.
Someone told me that those drives have a diode on it that dies when something goes wrong with the power.
It is possible to measure if that diode died by using an ohm meter, but than you have to know where to measure.
Tomorrow I will see the guy who told me that, I hope he does not only know this story, but also has some experience with it.
I sleep every night with my fingers crossed. ;-))

How could you connect the wrong adapter to the drive?

Very easy, I have four external drives attached to my LapTop, permenantly. But I was preparing to go on holiday for some weeks, and a friend was there to watch the house. I decided to remove my drives, for safety. Than my holiday was cancelled due to the unexpected death of a close family member.I needed pictures of that person who where on one of the drives. I connected the power, the connectors where te same (4 pins) and by accident I switched them.
Normally it should not cause a problem i suppose, but in this case it did, because the two drives ended up with the same problem.
And of course ...................... no backup!! Stupid, I know, but regrets always come to late.

"Actually I crossed two drives/adapters and both went dead"

Can you clarify that further.
What type of external drives are these, 2.5" or 3.5"?
Is AC current required to the enclosure?

You originally listed the drive as an internal drive. If it is an internal 3.5" in an enclosure specify that.

Yes, its an internal drive in an external housing.
Brand of housing is LaCie Poche.
I got the drive name and type after I opened the enclosure.
Is there a difference then between internal and external used internal drives?

What model of Lacie external drive is it?

You normally can't physically connect the power connector backwards, unless you use considerable force to force it in / on .

Have you dropped the external drive enclosure ?

You MUST provide sufficient power to external hard drive enclosures, or they won't work.

If it's a model with a 3.5 drive, you MUST use an external power adapter plugged into the external enclosure, and it must be working.

The USB port you plug it into MUST be able to supply the full USB max spec 500ma.

If the USB cable you're using did NOT come with the drive, it may NOT be sufficient.

If it's a model with a 2.5" drive, you MAY need to plug it into TWO USB ports, or plug into one USB port and use a 5v power adapter plugged into the enclosure if it has a jack for that. .

Troubleshooting USB device problems including for flash drives, external drives, memory cards.
See Response 1:

Check that out first.

Rarely, not all the ports on the back of a desktop case may be able to supply 500ma each.

If you have a desktop computer, Note that I answered a Topic on this site recently where a guy had an external drive, which does require the full 500ma, connected to a port on the back of a desktop case - it would not work properly when a webcam was in the port next to it, but it worked fine when the webcam was unplugged. Ports on the back of a desktop case often have two ports connected to the same USB controller module that are ports one above the other - you could try connecting the cable to one of those and leaving the other un-used.

If the external enclosure is damaged, it's likely the drive inside of it is still okay, more so if it's a 3.5" drive and if the external drive has not been dropped.

You can buy new external drive enclosures starting at about $20 for a 2.5" hard drive, or starting at about $25 for 3.5" hard drives. It must be for the same type of hard drive - EIDE (PATA), or SATA, or one that can be used for either.
I recommend Vantec ones.
