Multiboot XPx64, Vistax64, Svr2008: XP can't write to Vista HDD, WTF??

Hello,

I have a PC with three partitions on SATA master drive 1. I installed
three OSs in this order (all x64): XP, Vista Ultimate, Server2008.
They multiboot perfectly.

I also have a second drive, a standard IDE Maxtor 320 GB as an IDE
master. It contains about 250 GB of important data. I set up the
second drive using Vista.

I can't write to it when I boot into XP. I've tried to write to
several directories. I always get this error message:

Disk N: is write-protected
A file cannot be saved on a write-protected disk

XP has also called it "Disk T:"

It isn't write protected, AFAIK. My best guess is this error is
caused by permission incompatibilities between XP and Vista.

Any suggestions?

Thank you

Ray

change the permission using the administrator account.
