I have a maxtor one touch I 120gb external hard drive. I need a power source for it and wanted to know if anyone has one they would sell or can find the correct one on eBay for me. I believe they are 12v 3 amp. Thanks!

Welcome Ben 
At ebay just search for “maxtor one touch adapter”, then find one that meets the description of your old one. I usually sort them by price+shipping.
