My unit is not powering on. I plugged in an 18v power supply into the unit and it was on for a few seconds and then shut off. Did I burn out the unit?
This solution will be rather lengthy. I apologize for the length of it in advance, but feel it is necessary to explain my possible solution.
Please bear with me.
Inside the external harddrive case is a SATA harddrive.
The SATA harddrive plugs into a small circuit board, via an interface connector, OR small cables.
On the back of a SATA harddrive are metal pins that stick out. The ones to be concerned with are the 15 pins for Power, and the 7 pins for Data. The 15 pins for Power are grouped together, as well as the 7 pins for Data. An Interface is simply a connector that has socket holes in it, that the pins stick into.
If you have never seen a harddrive, much less a SATA harddrive, the above statement will be as clear as mud.
Let me show you the pins on the back of a SATA harddrive, to help clarify this,
Under the heading - Serial ATA Signal Assignments, view the illustration.
On the right you will see the Power Cable, headed towards the Power Connector. If you could enlarge this illustration you would see there are 15 pins.
On the left you will see the Signal Cable, headed towards the Signal Connector. Again, if you could enlarge this illustration you would see there are 7 pins. Signal is also Data.
(Data = Information. Information is processed back, and forth to the harddrive through this cable)
An Interface connector is rectangular in shape, and has socket holes to fit these pins.
Or, as stated above, it may have two small cables as shown in the illustration, and they plug into the Power, and Signal (Data) pins.
Either an Interface connector, or two small cables lead up to a small circuit board.
IT MAY BE that you are fortunate, and the circuit board bore the brunt of the overload of voltage, and did not get to the SATA harddrive inside.
My suggestion would be what I would do myself. This suggestion may not be what you would do.
I would open the external harddrive case, and look for obvious signs of electronics failure on the circuit board, and on the harddrive itself.
The harddrive also has a circuit board. It's on the bottom of the harddrive.
If you see obvious signs of damage such as,
1.Black marks on any of the various electronic components, or 2.Electronic components that have melted, swelled up, or look burned,
on the circuit board of the SATA harddrive, then you may want to stop here.
The 'cure' may be more costly, than the information you have saved on this external harddrive.
IF, the circuit board of the SATA harddrive looked good to me, I would risk a small amount of money, to see if I could get the harddrive to work again.
Again, just my personal preference, and not direct advise that this is what you should do.
I would buy an External Enclosure, and install the SATA harddrive in it. The External Enclosure also has a circuit board inside, and uses a USB cable to connect to the computer, just like the External harddrive that you have now.
Average cost for a decent external enclosure for a SATA harddrive is around $30 USD.
Here is an example, (Not an advertisement for the external enclosure manufacturer, or said website),
The external enclosures come with info about how to open the enclosure, and install the SATA harddrive.
Should you have gotten this far, thank you for your time.
