I have a similar problem with my 1tb wd ext HD. About a week ago I tried accessing files on it and it told me it needed to be formatted before the drive could work. So I did it against my will, loosing all 900GB of data I had on there.
But none the less it worked after that. a few days later MY comp wont recognize it but BIOS does, and in device manager the only thing I see that looks like ti could be the HD device is this "WD SES device" and there is a yellow bang or whatever its called next to it. The light on the HD comes on and stays lit. However it doesn't cycle up and down. It does that when the computer starts up. It flashes up and down then goes solid. When I plug it in the comp makes the typical usb plug in noise but still no E drive is found. I'm wondering if the fan may have stopped working and caused the HD to over heat and stop working. But I have tried everything and have had this HD for two years with no problems up til a week ago.
I hope someone can help me out, because I really need this HD.
Thanks
Randy
Also After looking through the device manager, I find in properties for the WD SES that the device is not working properly because windows cannot load the drivers required for this device and unfortunately the serial number is so small that I can't read it. What type of drivers would I need to fix this problem.
