Repartition and reformat under XP?

Ok, that is a problem. Best approach is to use a disk wipe utility
to clear the disk, restart and then partition and format under XP.

Since I do such things under Linux, I don't know what tools
are best for XP, but google("wipe disk") should find several
and the archives of this newsgroup should also contain relevant
information.

finger to keyboard and composed:

It appears that the MBR and partition table that XP sees is a dummy.
For a GPT disc, the real partition table is at sector 2, not sector 0,
and partition 1 starts at sector 34, not 63. AFAICT, if you want your
hard disc file systems to be visible to both XP and Vista, then you
will need to backup your data and repartition and reformat using NTFS.

See http://en.wikipedia.org/wiki/GUID_Partition_Table

"The primary purpose of the MBR at the beginning of the disk is to
prevent MBR-based disk utilities from mis-recognizing, and possibly
over-writing, GPT disks. A single partition, encompassing the entire
GPT drive, is indicated. The System ID for the partition is set to
0xEE, indicating that it uses GPT. Because of this, EFI ignores the
MBR. Some 32-bit OSes which cannot read GPT disks nevertheless
recognize this ID and present the disk as an inaccessible GPT disk."
