1)Windows shared space. Where is it?

[Trichy pasupathy]

1. I installed FC3 x64 on a separate drive in my windows XP system. At
the time of installation, I was asked a question as to how much space
I should assign on the drive so that Windows and linux can both share
files.  I remember to have assigned at least 20 GB. However, When I
boot from WinXP, this drive appears completely unformatted. How do I
find this 20 GB in both Windows and linux?

My appreciation to your responses in advance.
