I haven't tried it yet because historically it takes several times as long as just copying the data "manually", so to speak. I actually sent it back to Neuros and the were "unable to duplicate the problem". Since I have been able to duplicate the error message on two different computers, that leads me to believe that they just didn't copy enough data to see it (I usually see the problem after upwards to 4 GB have been copied- sometimes as little as 3 or as many as 7.) If it comes down to it, I may either buy a replacement HD and swap it out or wait until the Neuros 3 comes out and trade it in (if they do the same kind of trade program they did with the Neuros 2). I bought a Neuros on ebay and it did NOT go well. Mike H. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
