I am in the process of migrating files from a Dell laptop running XP to my new iMac. Essentially an easy task as all the files are on an external drive. I have 2 TB of storage on the iMac and thought it would be a relatively simple task to copy from the external hard drive to the iMac. After connecting the drive to the iMac I then tried to get the size of a directory on the external drive. I've been waiting about 15 minutes now and it still says "Calculating Size". Just after doing this I started a copy to move files from the external drive to the iMac. Unfortunately all I see at present is the spinning beach ball. Just wondering if there's a way of cancelling the copy process or of getting some status as to what is happening?
