I'm used to backing up data from my Xp computer to external usb hard drives every now & then. Recently I bought a new 3TB WD external hard drive but once I plugged it to the usb port, strangely enough it just appeared in the list of device manager (I can safely remove it from system tray) but not in the list of Disk management nor in the explorer!! When I try it on a Windows 7 computer it worked effortlessly. I'm suspicious that it is the transition from 512 to 4k sector size. Is there a trick that would enable me to use the device in Xp too? Would it work out if I reformatted it using Windows 7 utility to any specific allocation unit size?
Please help, Thank you
