Samsung S2 (Seagate) 1TB USB Hard Drive Mini Port Reapir?

Hi there,

Long story short, hard drive slipped off the table while connected the laptop and bent the pins in the USB mini port (HD didn't hit floor). I no longer can connect the drive via USB.

On opening the case, I expected to see the usual SATA connectors connected via the USB bridge/mini board - I was going to connect drive up to another enclosure I have and happy days.

However, I was presented with this (pics at end of this message) - it is designed with a "USB on Board" type configuration.

I have tried aligning pins back, but are beyond repair.

I see 3 options:

- remove and solder a new USB mini port (sausage fingers make me nervous on this approach)
- see if I can locate a replacement PCB for the hard disk? Understand it has to be an exact match?
- se if theres any faulty or parts only drives I can get on fleabay and attempt salvage/repair

I have no clue where to get a replacement board from or really how to go about either option (4 screws on the PCB)? Contacted Samsung, they gave me Seagate's number - they are closed for the next 2 hours, but will try later.

Hard Drive Details (what do I need to search for a part?)

Samsung S2 USB 2.0 1TB ultraslim Hard Drive

Model : ST1000LM026

Not sure where to get PCB number from :-(

MANY THANKS for our help.

Got some more pictures. Been in touch with a PCB supplier and they are very hard to got hold off this one?

Need help with the soldering in that case?

I can order anther mini USB port, but I am not sure where to solder?

Hi, any luck? I have same problem :(

I have been in touch with places that's specialise in PCB's from China - they seem to be able to get most makes and models, EXCEPT Samsung ones!!

This leaves me with 2 options:

1. I have received some parts I ordered and have a couple of mini usb ports to play with - try and unsolder/solder new one on board - the solder onto the circuit board is TINY (the 4 connections) plus I can't find a diagram so will have to take photos and try and copy what I see - to solder right ones, to right pins.
2. Buy another, exact same USB hard drive - remove PCB (only 5 screws) and put on original hard disk.

Now, the unmoral side of me, would see if I could open the case of a new hard drive without breaking anything, swap the PCB and send the new one back under warranty for a refund or replacement, rather than waste a payout and still left with one unusable drive.

OR, see if there's an broken one you can buy from ebay (has to be same mode and capacity).

Depends how much $£ or time the data is worth to you. If invaluable, just buy anther hard drive and swap the PCB - note you will void the warranty doing this, but will have a working hard drive.

I am now looking for a soldering iron small enough for the job, but happy to update you if it works and what parts I ordered (they are like £1/$2 each!.

In future I will try and AVOID any 'ultra slim' or ones that have USB on board! the traditional SATA drives are much easier and cheaper to sort out!

Sorry if my English is not very good.

I have had exactly the same problem, but with a hard drive of 500mb. The hard drive is of Freecom, although when you remove the shroud appeared Samsumg, the codes are similar to yours but it is something different (i'm guessing by the capacity). The problem is the miniUSB which began to leave behind to make connection and only connected by moving the cable, but now does nothing.

I'm two months in contact with Freecom in Germany since by law (European), must have spare parts for the equipment for 5 years after discontinuation of a product. But for the moment don't give me solution and say they don't have the PCB for given me (because I will tell you how it ends).

While I tried to put small wires on each hole of the miniUSB, and connect it to a computer, but it does not work, the problem is on the welds of the miniUSB and how they are micro-welds, i dare not to weld them myself.

If Freecom solution does not give me what I will try with Samsung. If you've found another solution, please, put it here. To see if between the two we got access to the hard drive.

This is my hard drive:

Hi there - nothing wrong with your English - that is the same that happened with mine - wobble cable, then eventually died - one of the ins is completely sunk inside the connector - No new, news I'm afraid. I did buy parts and have new micro connector.

I also bought a second hand one from ebay, same make/model, but the hard drive inside was VERY slightly different (same capacity, but different sticker on the hard drive :-()

In Samsung case I tracked the hard drive back to Seagate and they are Momentus?? model. Seagate have a forum on this model of hard drive, but not much help.

the solder is way too small for me to attempt to redo - it is all machined.

The only options I have are:

- Keep searching on ebay, until I get a match and sell the rest on
- Keep contacting manufacturers in China with photos of PCB
- Try and take ROM off of PCB and swap with the other one I have
- Try and find a circuit diagram and solder wires straight to board.

I have also found this useful article! May help?

I have started filling up the new drive now, so not lost all hope, but it is fading for getting the other one working - 'USB on Board' has got to be the most flawed thing designed!

Am considering getting a small NAS with at least 2 drives mirrored to save any future heartache!!

if you bent pins, unfolds them.
I done it. Cut the metal off connector to access to pins, and unfolds with care...

After, connect USB, copy data on an other drive.

I am French, so I don't speech very well English.

I'm not certain, but I suspect that a straight board swap won't work. I believe that the contents of the 8-pin serial flash memory chip need to transferred from patient to donor.

If I'm right, then you will be wasting your time purchasing your PCB from a supplier who doesn't offer a firmare transfer service. Instead your best chance is to find a local TV/AV repair shop that will reattach the USB port for you. You could use wirewrap wire for this purpose. Some users have even used a small vice to hold the connector in place.
