Seagate freeagent not recognized by computer

[Sueserle]

Usually I can plug in the Seagate Freeagent like any other USB but today for some reason the computer does not seem to recognize it is there. It has power, light is on and it has a low hum. Is here a simple solution?

Windows may not have assigned a drive letter to it, even though it did so on previous occasions. If that is all that's wrong you can assign one manually:
Control Panel > Admin Tools > Computer Management > Disk Management

In the bottom-right panel, find the bar which relates to that drive (it may say "Raw" and have no drive letter).
Right-click that bar and choose "Change Drive Letter and Paths"
Click "Add"
Choose a letter
Click 'ok'

If that is not the problem, test the drive with "SeaTools for Windows": http://www.seagate.com/support/downloads/seatools/
