Iomega external hard drives are used for transferring data to and from a computer and keeping it safe. When your Iomega external hard drive isn't powering on properly, you will not be able to back up your data. Power issues with Iomega hard drives are usually caused by problems with the power cord. Before you send your hard drive off to Iomega for repair, try to troubleshoot the power issue and get your drive back up and running.
