Problem: The hard drive icon doesn’t appear in Computer

Q: Is the hard drive listed in Device Manager?

A: All drives appear in at least one place in Device Manager.

Type 

Device Manager

 in Search to launch it. Look in the Disk Drives section and, if necessary, click the

Plus (+) icon to view the full list of devices. If you’re uncertain that your drive is listed, safely unplug it and
then reconnect it. The entry that changes is your Seagate hard drive.

Q: Is your hard drive listed next to an unusual icon?

A: Windows Device Manager usually provides information about failures with peripherals. While the Device
Manager can assist with troubleshooting most problems, it may not display the exact cause or provide a
precise solution.

An unusual icon next to the hard drive can reveal a problem. For example, instead of the normal icon based
on the type of device, it has an exclamation point, question mark or an X. Right-click this icon and then
choose Properties. The General tab provides a potential reason why the device is not working as expected.

Q: Is your hard drive mounting in the operating system?

A: Open Disk Utility at Go | Utilities | Disk Utility. If the hard drive is listed in the left-hand column, check
your Finder preferences to see why it is not displayed on the desktop (review the question above). If it is
grayed out, it is not mounted. Click on the Mount button in Disk Utility.

Q: Does your computer’s configuration meet the minimum system requirements for use with this hard
drive?
