After suffering with a useless Maxtor 160 HD, this WD drive works as advertised. I wanted a HD that you could simply 'drag & drop' files onto the WD desktop icon - saved & done. Files can then be recovered or reviewed easily by clicking on the same icon. The USB power source eliminates one 110 V plug in from your setup. A final plus - the WD HD is compact - 1/4 the size of the Maxtor!The Maxtor HD required a schedule for saving files - totally useless - it made a nice hum (so does my clothes dryer) & the entry screen appeared on the desktop, but it never worked!! Want to buy it cheap??
