Have a 1 tb buffalo external hd. worked great had it for back up. I unplugged it to move my computer. when I plugged it back in, there was no green light no power to the drive. check voltage and the power...


try to test it on other computer or laptop... if the unit are still exist maybe your problem would be the external drive..there are no switch button on it, because most of the switches are located on the adapter, the only testing you could do is to test it to other unit..If the external drive are ok once after you test from other PC's, then might as well check your USB port by plugging-in to other port...or try to use other power supply on your computer, co'z sometimes the supply can no longer supplied any voltage coming from your external drive once it plug-in..

Hi im just wondering which connector to put my power supply to and would a 240v to 12v inverter supply the right amount of power


Check the input voltage number on the power supply. Many cameras take 110 - 240 volts. If that is the case you do not need an inverter ... if the input specifies a voltage such as 110 OR 220 then that is the voltage you must have from your inverter. If you are stepping all the way down to 12 volts then the output voltagefrom the inverter must match the input voltage for the camera. It is best to use a recepticle adapter for your power supply and make sure the power supply input and the external electrical supply match or the external supply is within the range specified on the power supply..

I have a 1TB seagate expansion external hard drive and i was wondering if i had to plug it in to a power source other than my computers usb port. My teacher has has some really small one and that didn't...


Some do and some do not. if there is no power input jack for DC input then you don't need external power. The 5 volt supply to the USB will power it fine.

Dear Sir/ Madam, I have TWO Western Digital USB


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!!
Regards

What external power does SmartDisk FireLite FWFL120-N take?


Many USB power supplies will have the right plug. I picked one up by buying a cheap USB hub, What you want to look for (most likely on the bottom of the power supply) is VOLTAGE Output: 5.0 VDC, POWER Output: 1.0 amp or (1000ma) and the center hole is the positive side. I have even seen some BluTooth earpiece charges that supply what you need.

Hope that this will help.

I plugged my external hd into a diff electrical cord and it blew


I like the way you say "supposedly" normaly it is or isn't the same.
However , to the problem External hard drives contain a circuit board to supply the HDD with power and convert the signal from it to be used by a USB port. The Hard drive itself is exactly the same as the one in your PC.

Your external casing may be fried but the HDD inside it could be quite OK.

Please i need the power adapter rating for seagate


Have you got the original power adapter?
If so the voltage details are printed on the label on the bottom of the adapter.
If the external USB Seagate hard drive houses a 31/2" drive then it requires an power adapter that provides +12 volts and +5 volts both supplying approx 2000mA of current.
If the Seagate uses a 21/2" (laptop) hard drive then it only requires +5 volts power adapter.
The only problem is the power connector to the external drive, make sure it suits the external hard drive unit and the power pins are correctly wired for the Seagate. If the polarity of the plug is incorrect lt wired (ie reverse polarity) then it could damage the USB hard drive and adapter case.
