Hi,

I have Samsung HM322IX. In this drive is USB interface only, which was cut off - it was under connection via USB. After solder new miniUSB plug, drive is not recognize - standard popup "USB Device Not Recognized". Probably USB controller is dead.
I don't have other the same PCB on stock.

1. Does anyone know, where I should connect SATA on this PCB - pinout?
2. Maybe there is SATA PCB compatible with this one. Which?

Marry Christmas to all :)

The first thing I would do would be to verify continuity between the various pins in the USB connector and the pins on the USB-SATA bridge chip. To this end it would help to know the part number on the IC -- the USB Data+ and Data- signal traces disappear under the IC. Is it a JMicron, Initio, Oxford Semi, Cypress chip?

You may achieve easier access to the USB pins by connecting a USB cable and testing for continuity from the larger host end.

The SATA Tx/Rx pairs are easy to identify. You can see two thin pairs of capacitively coupled traces exiting the left side of the bridge chip and running down the board towards the MCU. To gain SATA access, remove the capacitors and then tap into the 4 inline plated through holes at about 10 o'clock on the circumference of the centre circle.

I believe these are the correct pins:

http://www.users.on.net/~fzabkar/HDD/HM ... _minus.jpg

The order of the SATA Tx/Rx pairs would most likely follow the same pinout as a SATA interface connector, to allow for a neat PCB layout.

What tools are you using to read this one with. Do you have UDMA. You can try this one on there it is now supported and should give you a good idea on how this one can work for you and what might be the problem on it. I had a lot of these in lately and seems that they are full of bad sectors on it and and bad media damage. Have not found so far too many problems in the USB PCB boards on them here so would check on the UDMA and see if you can go from there.

Yes, I have UDMA. But problem is with interface, not with bad block ;)
Thank you fzabkar, I check your hints.

A little attention and you could find yourself , compared with usual PCB.

Dr.Kiev
if you don`t mind me asking,,

How do you take such close image to the PCB clearly like that?
if Digital Cam what model?

Am wondering about such an issue like this.

and thnx in advance :wink:

The best method is to scan the pcb plate.

Yes, is looks ok. But i think digital camera is enough.

I have Power Shot A3100 IS. It costs about 100$. Example photo from camera:

I have the same drive with the same problem. Where can I get a second pcb so I can swap the bad one with the good one? I have searched everywhere online but I can't find where to buy just the board.

Mems if you cant follow the thread that has all the info needed to connect a sata coonector then your not going to be able to diy your drive repair. I dont see anyone laying it out better than it already is in tis thread. If you dont know which pins are tx and rx on the sata connector google will tell you in a heartbeat. You have to put some effort into this if you dont want to send to a pro for repair.

Hello all!

New to this forum but I'm sure I'd be hooked on this for a long time to come! It's the pandora's box to all my data recovery troubles! (of course with that comes hard work, not spoonfeeding)

Having a technical background I thought I would understand this thread easily. However it seems that I need a little bit more guidance. Can someone guide me a bit more and I promise I will do my own homework!

I have the HM322IX USB board which has been fixed pretty badly by a previous technician and I have a Sata Board from a HM320II. I tried swapping them over just it is and it doesn't work.

Does this mean that the solution is not a simple board swap, or am I doing it wrongly?
