I have a WD 500 GB hard drive and recently, Vista hasn't fully recognized it. If I plug it in I can find it in the device manager (and it makes the "USB in" sound) but it doesn't appear in windows explorer. The only way I can view it in explorer is if I reboot the computer; but as soon as I unplug it and plug it back in it's gone.

Here's the steps I've taken so far:

1) Tried the drive in all available USB ports.

2) Made sure all USB ports are functioning correctly

3) Tried the drive in another computer to make sure it wasn't the problem.

4) Deleted INFOCACHE.1 as some forums say it can lead to USB problems.

Please help!!

Try updating your computers chipset drivers.. Visit your computers manufactures website and look for update motherboard drivers or updated chipset drivers. Install them. Reboot and try again. if that does not work you could always try to re-seat the connections. open up the portable Harddrive and unplug the PCB from the hard drive then plug it in again.
