I inverted the 5v and 12v power lines on a sata power connectors and burnt 4 hard drives.
They may be recoverable but I need to identify the components to replace them.
These are 2 SMD that looks like resistors(maybe 0ohm?) and a TVS Diode.
I'll be very grateful to whom might help me in this.
Please, have a look at these pictures to see the components.

Thank you very much, I've read your TVS diode FAQ and I must give you kudos on how well is written.
I have many broken harddrive and I will try to fix the drive with a TVS from one of them.
I'm now concerned about what you say are inductors.
I'm good with the rework station but my electronic knowledge is very basic.
What is its purpose where it is located?
I assume as additional protection.
I'd like to replace them rather that wire link their place.
I have a L/C multimeter, how you would use it to measure the induction of the component.
I guess as a capacitor it cannot be measured on the PCB.
I want to save the drives, but I don't mind about their content because I've a backup and I don't want to spend money to buy new PCBs.
Again, thank you!
Your help has been very much appreciated.

The drives are working again!
One of them had the copper rails between inductors and in-power completely gone fused.
I had to use very thin copper wire to rebuild, a bit messy, but it works.
Thanks fzabkar, I couldn't have succeded without your help.
