RAID1 size issue with PDC20265

[paul moore]

Hi Heinz,

 Hmm, looks like I was right. His extended partition runs past the end of
the drive. This is caught by RC6 and is causing his logical partitions
to not show up. From what I can see, it looks like his partitions will
come back when the half drive size problem is fixed.
 On a side note, what do you think of an error message for the partition
overrun error. Do you want me to throw something together or do you think
it is worth it?
