I find that Partition Magic gets mostly confused when trying to deal
with non-Windows partitions. Not always, just sometimes. But, it
doesn't matter as the partitions seem to always work anyway. The
problem seems to be fdisk, which is a bit free and easy with where it
thinks partitions start and end. Partition Magic disagrees and
complains. parted does a much better job but is also trickier to use.
The reason why this happens has to do with how disks are divided up
into cylinders, tracks and sectors. Partitioning software represents
the disk as a nice regular structure full of pie-slice shaped chunks.
That's about as far from reality as you can get, which is why
programs often disagree about details. Experience tells me that as
long as the start and end of partitions don't overlap, everything
works out just fine anyway. So don't worry about it.
