Yeah, NTFS fragments files just like most other file systems--it's just supposed to be more efficient when indexing those fragments. (So, if the file system knows where to find the data ahead of time, it can avoid high-level seeks and allow the disk subsystem to perform an optimal read. I'm probably over-simplifying.) Assuming the drive has just been repartitioned and not formatted, it should be possible for a data recovery specialist or a good software packge to recover the MFT and the file(s) you need.
