Hello,

 

I am repeatedly trying to copy usb to usb using the Restore function in disk utility (ie, just copying the whole disk image)

 

I am also trying to unpack an iso onto a usb

 

However, each time I try, i get 1 of 2 error messages:

 

"could not validate source - invalid argument"

 

and  "could not validate source - error 254"

 

 

any ideas ?      thankyou
