Hi,

I have a Conner HDD that is damaged. It has been determined that the PCB is faulty. The drive will not start.

I have order another drive from EBAY but found out now that this may not work.

Is there anyone that can repair these PCB's

Hi there,

Don't know if you have a backup of this volume's data or not. Using that to a new HDD is the #1 best choice.

If you know for sure the problem is with the PCB, you can replace the PCB with an exact Model # & Rev # of a Conner HDD. It is finicky but can be done. The firmware on the PCB has bee low level formatted and timed by the manufacturer for the HDD, so if it's not exactly a replacement, it won't work.

You never want to open the HDD's cavity in that any microscopic dust will ruin it's function.

Here is a good review of PCB eval and repair:

It has been determined the PCB is faulty, but it has not been determined what is faulty about it, yet a second PCB wasn't tried with it. Interesting logic.

Start with the usual suspects - connections, solder, power protection (fuses, transient protectors), and power chips (motor driver, head positioner).

In most cases, you should exchange the BIOS/Main Controller IC before you swap hard drive PCB, in order to make the replacement board compatible with your HDD.

If your HDD can't spin, you can swap PCB to try. First you should find the donor PCB. If you do not sure how to find the donor PCB, please refer: http://www.hddzone.com/conditions.html.
