1st question: Do not compress the drive – this would slow down disk access speed substantially. Use the external USB to store new data. 2nd question: Copy your important files to the USB drive as a backup. As someone mentioned previously, you most likely have (the older, slower) USB version 1.1 and this can take a while, so be patient. Also, any discussion about replacing the hard drive is beyond this user’s ability (read first post). |
