I purchased my My Book Studio external drive about 6 months ago and when I received it it was formatted for MAC. I was able to get formatted for PC with the help of customer support. Since the very beginning I noticed that the drive would show up and over the course of the day it would disconnect on my old Windows XP station. I am trying to get it to work better on my Windows 7 (x64bit) station but it continues to be erratic. It causings my system to reboot twice and when Windows opens it not showing up as a device. I have to unplug the power and wait a few seconds replug the device and only then will it show up. I have downloaded the firmware driver which I have tried to load several times with no luck at all. Any help is greatly appreciated. Thank you.
