I have been told by HP that their hard drives have a factory installed bootable sector that can't be copied or cloned. They say I must use my recovery disk and build the new drive I wish to install by reinstalling all programs and updates. This is a real pain, of course. I am trying to find if any cloning software will get around this. If not, perhaps some software I could use to backup my original drives' programs and files, then restore them when I install the new drive. HP puts a basic Win X/P operating system back onto the new drive with the drivers needed for the computer with the recovery disk. (HP also puts two partitions on their drives. One is for recovery, and one is the bootable partition with the operating system. HP does not have any software to copy their drives.)
