I recently tried to store a 10GB file on a drive and it failed after only 4GB was copied. The reason was that the target file system was using a FAT32 filesystem and I was hitting the 4GB file size limit. You can convert a FAT/FAT32 file system to an NTFS file system without loosing any of the disk's content using the convert.exe utility that ships with Windows XP.

In the command prompt window (start+run+cmd), type: convert drive_letter: /fs:ntfs

For example, convert D: /fs:ntfs would format drive D: with the ntfs format.

Once you convert a drive or partition to NTFS, you cannot simply convert it back to FAT or FAT32, without erasing the whole disk.
