I have not seen any free programs that can retrieve or recover the files in dos mode. No way to retrieve or recover your files anymore. You have already formatted your disk. Since you have formatted your disk with NTFS format you won't be able to see this drive on dos mode.

I think what you should do is reinstall xp without tampering your existing partitions means as is. Just reinstall only your xp in C:\drive and then the existing partitions are still intact.

I've found Data Recovery Wizart, it isn't free, but it recovers data from formatted drive. If you are interested in it, look at link:
