I'm running Windows Vista Ultimate, and i have a "Western Digital My Book Essential Edition WDG1U3200"-USB harddisk.
Now at the moment vista refuses to recognize it, and when i plug it in, after a while i hear the "du ding" sound as if i placed something in the usb port, and when i pull it out i can hear the "du dong" as for the USB-out sound.
For a few days ago it worked, and for a few more days ago it didn't seem to work. Seems like it's coming on and off all the time.
If I then push the harddisks usb cable into the usb port i can go to "Safely remove hardware" and select it, and it even represents by name! Also the disk management in device manager finds the 300GB partition, but i can't assign a drive letter. I can also, if i place my hand on the harddisk, feel it spinning around, so it is running. Also Vista should have correct USB drivers, and all there is on Western Digitals website of drivers is some Win98 ones.
I also have a multiboot with Boot Magic, using XP and Vista.
This seem like a very odd problem to me, and i can't figure out what's wrong, and how to fix it.
