I run XP Home with two disk drives. Using Acronis I cloned disk 0 to disk 1 & kept the clone up to date. Yesterday an attempt to alter the partitions on disk 0 (with Paragon Partition Manager) went wrong & disk 0 became unbootable. Swapping over to the clone got everything back to (more or less) as was. However neither XP nor Acronis now see the old disk 0 (which is now disk 1 of course) although Belarc does. I presume disk 1 needs reformatting but how do I do this if XP can't find it?
