Trying to load a system image onto my desktop from a WD Passport but System Repair Utilities won't recognize the device. Keeps asking me to install the driver -- "Insert the installation media for the device ....". I've found a great deal of on-line chatter about this problem but haven't yet got a clear understanding of how to do it (I'm a techi novice alas). What exactly is needed and now do I get it ?

Many Thanks
