How to troubleshoot an iomega portable hard drive

Updated April 17, 2017

Iomega is a company that produces external portable hard drives. Their ZIP drives, featuring 100 MB disks, were extremely popular in the late 1990s, as they were one of the easier ways to move or backup large files. The popularity of ZIP drives waned in the early 2000s as the use of writable CDs spread. Now, Iomega primarily markets hard drives that can store more data than a CD-R. If you are having problems with your Iomega hard drive, there are a few things you can do to troubleshoot the device.

Check the USB connections from the portable hard drive to your computer. All Iomega portable hard drives connect to your computer via a USB cable. Unplug the cable from both the drive and your computer and reconnect it.

Ensure that your drive is receiving power. The power light on your Iomega hard drive should be on. If it is not, restart your computer. Some Iomega portable hard drives may have a power switch. Switch the device off and switch it back on.

Reinstall the drivers that come with your portable drive. Insert the CD into your computer's CD drive. The drivers will automatically begin to install. Follow the on-screen instructions to complete the installation.

Check that your USB hub is receiving power. If you are connecting your drive to a USB hub, switch the hub off and on. If it is not receiving power at all, unplug the USB hub from your computer and reconnect it. Restart your computer.

Plug your portable hard drive directly into your computer's USB port if you are using a USB hub and the drive is performing slowly. Ensure that your drive is connected to a USB 2.0-compliant port.


Iomega portable hard drives may not be automatically assigned a drive letter when connected to older computers. You may have to manually assign a drive letter to the portable hard drive using the disk-management tool in the control panel.
