- I have an Iomega eGo external hard drive which works fine with Windows 7. I have read many posts regarding this issue, but can not find a solution. The Hard Drive is not recognized, however I do hear the iOmega beeps when plugged in just like it does on my Windows 7 laptop. There is no way to display it's content in Windows 10. I have connected.
Password Protection / Encryption The eGo Portable Hard Drive includes hardware-based 256-bit AES encryption that allows you to password protect the drive to encrypt all data stored on it. To set up and use password protection, you need to download and install the Iomega encryption utility. See the support area. Leave it connected and then go to Utilities Folder and open Disk Utility. In Disk Utility on the left side, click on the Iomega Hard drive, but not the Named drive just below it. On the right side, choose Partition and then choose One partition from the pop-up. Click on Options button and choose GUID as the partition type.
When you format an internal or external storage device, you can encrypt and protect it with a password. If you encrypt an internal device, you must enter a password to access the device and its information. If you encrypt an external device, you must enter the password when you connect the device to your computer.

If you encrypt an external storage device, you can’t connect it to an AirPort base station for Time Machine backups.
