Can one tell me if the maxtor ext hard drive runs on 12v ac or dc

all external hard drives that need a power adapter use 12v

You can find a power cord for your Maxtor Personal Storage 3100 100 GB Hard Drive here:

The ratings will be 12v ac 1.5 Amps output

Power Requirements

Input Frequency: 47–63 Hz AC

here is a link to the manual : http://www.seagate.com/staticfiles/maxtor/en_us/documentation/data_sheets/onetouch_data_sheet.pdf

Hi,

Sata drives use both 5V and 12V power. The standard SATA connector found on most current power supplies carries both. If you're trying to rig up some temporary power just hit your local PC shop and ask for a Molex to Sata adapter that will connect your old power supply to the new drive or pickup a USB to SATA adapter kit as they usually have there own Sata capable power adapter.

Hope this helps FixYa,

Chris

I've been searching for a replacement as well. I found the specs on the original cord at the following site.
http://www.libertye-online.com/servlet/the-1642/new-APD-I.T.E.-POWER/Detail

12V, 2A, positive inner post, 2.5 inner diameter (ID) and 5.5 outer diameter (OD).

I don't think I would buy the exact replacement ADP brand fom the site above. Many have complained about it failing at the 2-yr point. I am considering the following replacement from the same website.

NOTE: the input AC voltage range is different on this one, but it should still work in the USA.

There are other options on ebay.

Let us know if anyone has specific success with any of these or others.
