Hello,

If it is rated 5V DC, then the usb cable alone should be able to power it.  Just to be sure, what is the exact model # of the hdd?  As for amps, probably 0.5 at most or 500 mAh.

Does the drive power on?  It may need to  be initialized and formatted before it shows up in explorer.

i never power my drives from USB - you can easily overload (or burn out the USB section) since the supply is 5V at 0.5A MAX
since it can be powered from USB that is what you need for a power supply :0.5 A MIN, you can use a power supply that delivers more though, eg 5V at 1 or 2 Amps (the drive will only take 0.5A from it)

Knowing the exact model of the drive you can find easily which power adapter it needs. Look at the bottom of the drive there must be some info about it.

in response to noxcho, I have looked all over the iomega but there are no listing of any power requirements.  Only at the power outlet, it says 5vDC.  It is a 160 gig Iomega ext drive, and I have not been able to get the help of support because it is outside the warranty period.   I tried the local Radio Shack, but they do not have anything that has 5v and about  0.5 to 1.5 amp.  Thank u.

I'm surprised RadioShack does not have that.  Usually they have a universal adapter that has a custom connector such as a G or H connector that would fit the drive.

Again, what is the model number of the drive?

in response to Nobus, yes it is a similar model, I they go by serial numbers, but mine is also 160 gigs 400 ...
Your post, suggests the ampheres, but google does not carry the 5v at the diff ampheres u listed.  I wonder if there is an internet source to buy these power sources.  Thank u.

almost all 5V adapters will work then, from 0.5A and up, as i posted above
does it have a separate power connector? if not, you have to use the USB as power source
if that does not work (like many) use a powered usb hub like this : http://www.belkin.com/IWCatProductPage.process?Product_Id=158910
