I had recently purchased a 250 GB external harddrive, I want to copy my existing files to that. I face a problem of time delay in copying the files my existing harddisk to this external drive. eg., 700 mb of rar file which is in my F: drive when I extracted in the same directory it took 1 min to do whereas the same process it took 20 mins when I copied it from F: drive to G: drive ( external drive). can any one explain me why this delay & how to recify it.
