My expansion portable drive p/number is 9SC2NK-500
S/NUMBER is 2GH5VX5D (1.5TB)
This is a pretty new hard drive!
I bought it today and recently when I connected, this drive is not recognized in Windows XP SP3.
The following are my observations.
- Green light keeps on flashing.
- I get NEW HARDWARE FOUND message and then, after automatically installation of the new hardware was finished, тew equipment is not visible in my OS.
- I have tried changing the USB cable, but not much of use.
- I have tried connecting to different USB ports INCLUDING the back of the Computer case. SAME RESULT
FOR EVERY PORT.
- Device manager shows an UNRECOGNIZED USB DRIVE with YELLOW color.
- In Windows DISK Management and Windows explorer the drive is not displayed.
Any help is appreciated.

Its funny because the same drive was working just fine attached to my laptop few weeks ago. It powered fine then?
The expansion portable drive requirements are USB 2.0, if what you are saying is true (USB 3.0) then Seagate guys must be wrong.
Anyway, I have to try your suggestion.

It appears that Windows is detecting the USB-SATA bridge chip in the enclosure but not the hard drive behind the bridge.
If the drive is powered from the USB port, then it may be that the port is unable to provide enough current to spin up the drive. USB 2.0 ports are current limited to 500mA whereas USB 3.0 can provide 900mA. A typical 2.5" drive requires about 850mA during spin up.
If a USB 3.0 port is not available, then try a USB Y-cable. This will pick up power from two USB ports. Alternatively, try a powered USB hub.
I use USB External drive guided Troubleshooter.
Step by step.
And i was trying to use different cable and power supply (also USB Y-cable) but nothing happened. Maybe because the length of Y-cable has been longer then the original mini-USB cable.
But the drive spins up and I hear his noise and light vibrating.
Thanks for the advice but I have decided to change this drive to another
