I have a western digital 500 gig external harddrive and it was separated from its DC inverter. We cannot find out the voltage to determine which DC inverter goes with the hard drive and am therefore unable use it for fear of using the wrong one and blowing it up. Can you help us determine which one would work? It is just sitting here on my computer unused. My e-mail address is [email protected] and my name is Gloria Travis Thank you

It's dead. Time to buy a new hard drive...

Mine came with an 12V DC, 1.5A, 18W adapter from Ktec. The same can be found on Amazon. take a look: Stop searching Start charging like pro I hope this was helpful. cheers

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!!

You better check with the Seagate people. This seems to be a problem with the casing. And since you're under warranty, you can get a replacement.

Did You Try Using The Included AC Adapter To Power It Up

Could average around 12V I believe.

First off, have you downloaded ANYTHING onto that hard drive?

Take it our of the external encasing and plug it in directly to your motherboard. This has worked for me in the past. I just had my second wd external harddrive crash so now I will do the same process all over again.

Hi

Is it showing the 300gig in the properties? if yes then try to copy with command mode,If again its given problem then u need to backup your data and format the drive, then try copying.I think it will work.

hi there, from what you are describing u have problems with the harddrive plotters so you have little time to save data. using the program get data back for ntfs or fat you can format your harddrive and block bad sectors from your harddrive and with the program mentioned above you can recover all the information you had on your harddrive.

give it a try
