How to recover data from iomega external hard drive

Check in Disk Management as it may just need a drive letter assigning to it:

Control Panel > Admin Tools > Computer Management > Disk Management

Look at all the horizontal ribbons in the bottom-right panel. If your Iomega drive is shown there (it will have no name, no letter, and may be labelled "RAW"), right-click it and choose "Change Drive Letter & Paths".
Click "New"
Choose a letter.
Click 'OK'

If it's not listed in Disk Management it typically means the drive or it's converter-board has failed, and no recovery software will help you under those circumstances. You can try removing the drive and buying a third-party external enclosure for it, or send it to a data recovery specialist firm (but that is very expensive).

Since it might just be an enclosure problem you could take the drive out and connect it directly to your motherboard with sata or ide. Then if it doesn't work you know it's the drive itself that's dead. Good luck.

Can you see the external drive on your Computer window or is it not visible? You can try EASEUS Data Recovery Wizard Pro. I used it a year ago when my external drive failed and it managed to retrieve nearly 80% of my data. It took more than a day to finish (depending on your HDD size) but eventually I had my data back.
