Is the drive IDE or SATA? If IDE all you may need to do is set the jumper to slave.
I swapped a hdd from one computer to another, it was working fine, but wouldnt even spin up in the new computer.
On inspection it looks like I have damaged it somehow (see pic)
If i join the broken end back to the board is it likely to fix it while I get the data off or am I likely to do more damage ?
Would it be better to try and get an identical drive and switch the boards over ?
Thanks thomo

I'm out of my mind, but feel free to leave a message...

SATA and it is not spinning up at all
It's marked '4R7' which is a 4.7ohm resistor so try measuring its value with a multimeter. Such a low value would be typically be used to monitor current in a circuit and it appears that it got hot enough to melt the soldering which indicates a major overload occurred possibly in the motor itself so a replacement board of the exact same model might fail the same way as well. That would leave swapping the disk itself into a good drive as the only way to extract data from it (clean room etc etc).

Have a go at repositioning it if you can without short circuiting it. I doubt the drive will get any worse as it's already a paperweight
This is where backup images are a lifesaver.

I do believe the component in question is an inductor. The 4R7 marking is unfortunately misleading; the wire still bonded to the PCB gives a clue to its function.
If you merely decapitated the device, by all means solder it back in place. The SH6125B IC is the spindle motor and voice coil drive IC. Unfortunately the TI datasheet seems to be made of unobtainium.
The heavy copper trace and via stitching around both coils point to their use as suppression devices.
No power = no motor drive. Solder it back in and see if the magic smoke comes out.

Not pretty I know but somewhere under the hot glue is the broken resistor and some bad soldering but to my surprise it spun up and is working.
Well it worked long enough to remove the data so if it fails again I will be prepared
thanks thomo
