Any idea for this curious phenomenon?

Hi all,

About 2 months ago, I used that desktop docking station for reading hard drives in a convenient way.

That device just burnt my lab drive and any other drive which was inserted in to it.
The salesclerk from the shop test it too on his new hard drive and it was burnt too.

Today (after 2 months) I pluged the burnt drive to a power source and found out that it come to live without any reason. seems like that docking station didn't burnt the drive but freezed it.

Could be such thing?
Any ideas?

So it sounds like the original diagnosis of "burnt drive" was wrong, because you are now saying that the drive is OK. More technical details needed from you IMHO, for other people to get an accurate understanding of the situation, as you are requesting... You can see/test/diagnose the docking station - we can't!

Perhaps you should start by explaining why you originally diagnosed that the docking station caused drives to be "burnt"?

I test the drive afterwards with Atola and PC3000 both of tham showed that the PCB is dead.
The man in the shop took a new drive from his stock, plug it in and bang! it stopped work too after that.
So he gave me my money back and sent the dock station to RMA.
Now the drive is alive again, Weird

You described the drive as "burnt" originally. That is not the same as "dead".

Which component(s) on the drive PCBs were "burnt"? What measurements did you make with a multimeter / oscilloscope etc. at the time of the original problem, to diagnose the exact fault?

Didn't do any test with multimeter or oscilloscope. The drive just stayed cold without any motion after plug in to power supply.
Can't explain it, but this is the same action which was happen to the guy in the shop (so he gave me my money back and sent the product to RMA).

That's a shame. I have an idea what might have happened, but without evidence (e.g. measurements of TVS resistance etc. using a multimeter, of the exact original problem caused by the docking unit) there would be no way to confirm / deny / evaluate my theory...

What is your theory?
I am interesting to hear
