1TB Windows Hard Disk marked as ext4

[nelioabreu]

Hi there,
I have a 1TB hard disk, external, that was partitioned and formated under Windows as NTFS. A bit later that same hard disk was connected through USB to a Fedora 14 system. Now I need to access its contents back in Windows and I can't. Windows doesn't recognize the partition. Under Fedora, the hard disk is marked as ext4 partition. How can I revert it back to Windows without loosing its contents?

Thanks.

When was the data added that you wish to preserve, exactly?
A GNU/Linux distro does not just "mark" a partition as one file system, it had to have been instructed (unwittingly or not) to create the file system.
I suggest backing up on DVD and re-creating the partitions in Linux, having one large partition as common between the two OSes in the FAT32 file system. NTFS is a dirty file system and does not play well with GNU/Linux. It can be done, but why?
IMHO one has to have a very compelling reason to do so.
I remain unabashedly pane-free!
