here is what I would do. install winows XP on the old disk and DO NOT activate it with Microsoft. Next, use it to gain access to the new drive and recover as many files as possible , and burn them to CD(s). Then remove the old hard disk, and reformat and install XP on the new hard disk. Copy the burned files, and activate Windows XP. Then disconnect the new hard disk, and connect the old disk and install Win98. Now you will have two restored hard disks.
