|"NTFS has five released versions:"|
(and # v3.1 has 3 "subversions")
"# v1.0 with NT 3.1, released mid-1993
# v1.1 with NT 3.5, released fall 1994
# v1.2 with NT 3.51 (mid-1995) and NT 4 (mid-1996) (occasionally referred to as "NTFS 4.0", because OS version is 4.0)
# v3.0 from Windows 2000 ("NTFS V5.0")
# v3.1 from Windows XP (autumn 2001; "NTFS V5.1"), Windows Server 2003 (spring 2003; occasionally "NTFS V5.2"),
Windows Vista (mid-2005) (occasionally "NTFS V6.0"), Windows Server 2008, Windows 7.
While the different NTFS versions are for the most part fully forward- and backward-compatible, there are technical considerations for mounting newer NTFS volumes in older versions of Microsoft Windows. This affects dual-booting, and external portable hard drives."
One of the differences for the NTFS 6.0 used in Vista and Windows 7 is NTFS partitions can have sectors larger than 512 bytes - all previous file systems (software partitioning systems) have a max 512 byte sector size.
I assume XP can't read the data on a partition if the sector size is larger than 512 bytes, but Vista can read NTFS partitions made with an older version of NTFS fine.
That can cause problems on a multiboot system.

Apparently you can also have the problem of a Vista partition disappearing if not all partitions were made by Vista....
The partition that hosts Windows Vista may disappear if you use Windows XP to create a partition on a computer that has both Windows XP and Windows Vista installed
