You probably need to go to Windows Disk Management and partition and format the disk there.

At first glance, I expected it would be a cabling problem (power to the drive, but not a good USB connection to the PC), but I checked the Seagate site, and without having more detailed info from you about this particular drive, it would seem that it is supposed to be "USB-powered" -- meaning it gets its power exclusively from the PC. Quote:
"USB-powered - Certain drives do not draw power from a power cord. They simply connect to the computer via the included USB cable and the USB port provides the data connection so that data can move back and forth between the drive and the computer, and the USB connection provides electrical power to operate the drive. Some of these drives have a 2-pronged USB cable, and most computers will provide enough electrical power when only one of those prongs is connected, but some computers will require that both prongs be connected to provide enough power.

If your device is USB-powered, you should certainly have informed us about it from the get-go. We need that info confirmed-or-denied.

i had similar symptoms recently:
after plugging in the cable the little green LED on the seagate drive started to light. good. but windows wouldn't detect anything.

it turned out that it was a cabling problem, indeed:
after firmly pushing the mini connector into the seagate case windows suddenly detected the drive and everything was working fine.

so the green LED just indicates: OK, i'm now getting power over the USB cable.
but it does not necessarily mean that an active data connection between the drive and the computer has been established.

i just don't understand why it's required to plug the cable in that firmly.
you may also want to check the socket / usb port at the seagate case: it's a portable - some dust may have accumulated in there preventing a proper data connection.

We will never know what the problem was because Leon didn't bother to post back at all.
