I incidentally plugged a wrong adapter into the power... the hard drive was running but when i realized i switched it to right adapter and it is not working since then.. Could you please help or suggest a repair service center?
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

I believe the factory originals are champion brand, and would have been platinum, but it should still run decent with the coppers. The only thing I can think of is they are of the wrong gap. Copper plugs do not come pre- gapped at all and need to be done by installer. The gap for your stratus, if it's a 4 cylinder is .050. Wrong gap will cause no power and shaking. Correct champion number in copper is #443, and should say that on the box/plug.
If this external hard drive uses a power adapter and when it is plugged into the mains socket and you do not get a blue light or hear the hard drive spinn then most likely the power adapter is faulty and cannot supply power to the hard drive.
The hard drive needs a proper regulated power adapter for the hard drive to work. If the hard drive is a 5.25 inch drive it requires 12 volts and 5 volts power supply. If the hard drive is a 3.5 inch drive it requires a 5 volt power supply.
first of all , you are looking at the wrong voltages. The important voltage is the DC OUTPUT, which is the voltage the external harddrives use AND the polarity of the plug attached to the harddrive end of the cable.
if both the harddrives have say 12v dc output and both have the insignia of the center conductor being + (posative) then you can interchange them. and you CAN run a 9volt unit with 12volt DC power, but not the other way around.
Look at your power adaptors again for the OUTPUT and polarity.
should be a half-circle with lines depicting the polarity(+,-) of the center and sheild connections to the hard drives printed on both the harddrives and the power adaptors . This can also be tested with a dc volt meter while the adaptors are plugged into the wall.
DO NOT try to test the AC end while plugged in!!
This is bad news, the smell you have noticed from the ThinkPad is most likely caused by an electrical short in the power circuit and the cost of repair would not be a cost effective solution, a replacement motherboard may not be available because of the age of this model ThinkPad.
You maybe able to retrieve your data from the hard drive by removing the hard drive and connect to an USB hard drive adapter then connect it to a working computer's USB port. This computer will see this drive as an external USB hard drive and you can copy the data off this hard drive.
Couple things. What model WD drive do you have? Plugging the laptop adapter into the drive chassis may have fried the chassis. You can buy a new chassis and put your drive into it, or you can buy a new power supply in case the one you have has gone bad and you did not realize it. Not likely though.
The power requirements are very specific and the laptop power supply may have been to much for the WD drive.
I would sure enjoy helping you figure your problem. I've taken Electronic courses in the Navy and in college, so this shouldn't be too hard.
As far as the capacitor goes, manufacturers make several different products from the same PCB layout, just some don't have all the components. Once I see where the capacitor should be I can tell you if its necessary or not.
For the fuse, it sounds like there is a short somewhere further in the circuitry. Rather surprised it blew right off the bat, but people and machine alike can make mistakes when building things. I fixed a laptop power supply where they didn't even solder the source resistor for the switcher.
Upload your pictures, and we shall we what we can do with it!
You need to make sure that you get a compatible power adapter for that model. Most of Acomdata external drives use a 12v adapter, but not all. If you plug the wrong voltage into the drive, you do have the possiblity of frying your external. I'd check with your manual or post back your model number so I can look that adapter up.
i own the exact same drive. i'm looking for a spare power supply, came across this website, and saw your problem. the power supply is 12 volts dc at 2 amps. the connector that gets plugged into the hard drive: center pin is power (positive) and outer "shield" is ground (negative). hope this helps.
