when my western digital mybook 3TB (WDBACW0030HBK-EESN) is (directly) connected to the computer’s usb port, the booting procedure hangs on the windows splash screen.
the bios boot-up sequence is correct, after all the booting does get past the bios boot-up, reads the MBR, and then proceeds to loading the OS. it is there where the booting process gets stuck. (perhaps more precisely, it hangs while loading the OS. the OS loads normally with the drive unplugged.)
furthermore, in windows (when booted into it whilst the drive was unplugged), the drive seems to take a couple dozen seconds to appear among other drives present on the system; also, it then takes unusually long for the drive to respond after having been inactive. (by the way, i have disabled all the ‘power off usb port to save power’-options under windows>devices>system.)
i am using windows 7 (x64) on an intel core2quad system.
i have the latest windows SP installed. i have also installed the respective WD (SES) driver, as well as the latest firmware. i do not have (and never have in the past) installed the smartware software after reading the reviews and anecdotal stories.
thank you for you help or suggestions!
