fuzzy hot backup

Hi,
I'm trying to do a restore/recover to a point in time from a hot backup in 10.2. When I opened (reset log) the database, it complained that datafile 1 was fuzzy. What view can I use to check which datafile has a different checkpoint scn or what the issue is?

I ran the following query and it appeared that all data files have the same SCNs. I thought with fuzzy backups, the checkpoint scns of data files are different which in my case, they were all the same.

Can someone help?

select file#,checkpoint_change# from v$datafile;

     FILE# CHECKPOINT_CHANGE#
