I had to replace the power cord for my macbook a few weeks ago (cat chewed through the old one). My macbook is from 2007 and I am running OS X 10.6.8 on it. Since I have been using the new power cord, my external hard drive is not showing up in the Finder window and Time Machine cannot find it when I plug it in. I used this hard drive with no problems for two and a half years before this. The light on the hard drive does blink though, and it seems to be trying to do things. I looked for it in disk utility and it shows up there, and is properly formatted according to the user's manual (Mac OS Extended Journaled).
Needless to say, I haven't been able to back up in a while (and it's freaking me out). I am not sure if the new power cord is the culprit, but it's the only thing that has changed, and looking around online I have seen some indication that the amount of power getting to the external hard drive could be an issue (if the new power cord is faulty or something).
The hard drive is an iomega 320GB Prestige USB 2.0 Portable Hard Drive. It has a USB cord with two USB thingies on it and no other power source, although it does have an outlet for a power adaptor (which I don't think came with it).
Any ideas? I'm on my third hard drive for the macbook itself, and have learned the hard way to always back up, so I need to solve this asap.
