I am having two hard disks(20GB and 80GB).
One having Linux installed and other Win XP.

I would switch to either of the OS by plugging the power cord to the HDD
and unplugging the other.(to avoid conflicts between the OSes)
When i connect both power cords and boot to XP I can't see
the 20GB HDD(maybe coz' its using different File System)

Now the problem is i want to format 20GB HD(having Linux installed)
so that i could use it in win XP.

How can I do this?.
Please help.
Thanks in advance.
