Hi. I have had this problem a few months ago last time I re-installed my OS but now having just formatted my Windows partition again, the same has occurred and I cannot remember how to fix it!
The story is:
1. When windows is being installed and asks which drive you would like it to be installed to, it finds the second partition and the correct free space details of it etc.
2. An external cd run from boot program (Acronis Disk Director) will find the partition and show that it has files on it and the appropriate free space.
3. When windows is loaded and I look in my computer or disk management… there is a partition but a completely free one that has no file system!
As I say I solved this problem before after many days and I think it was just pure luck but I have no idea once again!
Thanks for your help, in advance!

P.S. Do you think this might have something to do with the RAID drivers at all?
