My Iomega LDHD250U 250 GB USB External Hard Drive's Power and Usb ports WILLNOT CONNECT!!!!!!! Please help ive been trying to figure out why all day.


Dear Friend, Your I-Omega case might be bad or the controller inside that connects everything. I suggest you to get: http://www.walmart.com/ip/Apricorn-Universal-Hard-Drive-Adapter/10811435. and pulled your hard drive enclosure apart, then removed your hard drive and connect with the external adapter. Usually comes with a SATA or IDE connector for data and power adapter. After connecting everything plug into your PC and it should be able to recognize.
Good Luck#

The computer won't recognize the simple 250 with just the USB plugs


It doesn't require a power supply You may need to install a mass storage driver. What operating system are you using? Vista? XP? Win7? Win8? 32 bit? 64 bit? Was the drive used on a Mac? Are you on a PC right now with it?

My Seagate Free Agent GO is not working. My laptop does not detect my external hard drive and external hard drive does not power up. Before it used to work good.


Either the power outlet it is plugged into does not have power or the AC power adapter for the drive has failed. Try another outlet. If that doesn't work see if Radio Shack has a replacement AC adapter or contact Seagate to replace it.

I hope this helps.

Describe your Western Digital 250GB MyBook External USB 2.0 250 GB Hard Drive Problem Do you have a picture of the voltage and amperage adapter for the Western Digital 250GB MyBook External HD ?


I don't have a photo of the AC adapter, but if you look on it the Voltage and Amperage specifications are;

Input: 100-240VAC / 50~60Hz
Output: 12VDC / 2A

This means the Input power can be from 100 volts to 240 Volts AC, and at 50 to 60 Hertz

The Output power is 12 Volts DC at no more than 2 Amp's. (Amperes)

Asian Power Devices Inc. has a model DA-24B12 that fits these specs.
Also a Wattac AC adapter model number - BAO362Zl-8-A01 will work.

Otherwise just use a 12 Volt, 2 Amp power pack, with a positive on center contact, and a 2mm pin hole

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

IF POWER ADAPTER IS YOUR SUPPLY IT MAY BE BAD. IF DIRECT TO 115V THEN DEFECTIVE.

No Power to External Hard Drive


Do you have access to a multimeter or voltmeter? If you do you can check the voltage coming out of the adapter and make sure it matches what the power adapter says it is. If it doesn't, then it is the power adapter. If it does, then it is the drive or enclosure.
