Dual boot, and reformatting existing partitions from FAT32 to NTFS

I am dual booting. I have 2 HDs (hda and hdc) with 1 partition on hda formatted as NTFS with the rest (except for Linux) as FAT32, On hdc I have a Reiserfs partition (data1) with the rest as FAT32. I now want to reformat at least 3 partions (say 2 on hda and 1 on hdc) as NTFS. If I altered fstab to reflect the partitions I want to reformat as NTFS file system BEFORE I exited Suse and then formatted them as NTFS would I have a problem in having them correctly recognised when I booted back into Suse? Or would I need to do a pretend run of the partitioner after booting into Suse and read-in the partition table in case the beginning/ending sectors are altered by the reformatting?
