Don't use Windows! (ever that is:) First fix your broken partition table.
Windows has trouble with big disks, and tents to use the wrong sections
of the partition table. A fast and sure way to fix it is to tug all your
linux partitons safe and comfortably in a linux extended partition (type
85) instead of the default DOS-extended partition (type 5).
By the way, this problem has nothing to do with linux/windows, it's
a pure windows thingy, you can even find info on it on Microsoft's
web pages.
This has been reported by David Henningsson <a@davidh.df.lth.se> too,
see list: debian-user@lists.debian.org
