I have a WD My Book Essential 320GB (green light).
It works perfectly fine on two of my Win XP machines but I cannot get it to work on my Vista Machine. It has previously worked on this machine, but now when I plug it in, the light comes on, and the PC makes a noise as it has recognised a USB device has been plugged in, but the HDD does not appear in device manager / computer / disk manager.
I have tried a number of things including :
-
Different USB leads
-
Different USB sockets
-
Deleting infcache file from \windows\inf
-
Replacing USBSTOR from \windows\inf
-
Running the Ext-HDD on a version of Windows 7 on a seperate HDD in the same PC (which works).
-
Viewing the Ext-HDD in BIOS (which shows it as a possible boot device, although it has no OS on it).
The same machine will mount a WD My Passsport fine, or any other external storage device…Just not My Book.
Any ideas?! Really stuck with this one…
