I have tried copying files from old HDD to another folder on the new HDD, and then transferring them from the new folder.
It seems to be transfering the files (after I have press 'yes tol all' for replacement) and the counter in the bottom left corner of the folder status bar increments when a new file is copied in........but then goes back down to original figure i.e. when no files had been copied in.
I must also point out that the old HDD was formatted in FAT32, and the new HDD in NTFS. Some of the advanced file options are different
