Well, the convert tool has converted plenty of filesystems for me without damaging data.
There's no need to emphasise WITHOUT like that. We're not stupid.
How to use the convert tool from the command line
(Assumes drive letter is C, change as needed)
VOL C:
Note the name of the disk in the first line, and the Volume Serial Number (for example, 3F4E-2D1B) in the second. Then type:
CONVERT C: /FS:NTFS
It will ask for that name in confirmation. Then it will ask two further questions. Reply Y each time to set up conversion to happen at the next boot, then restart the machine. (If you are converting a partition other than the operating system’s partition, you may find that it runs without rebooting.) After returning to Win XP, the hard disk will work for two or three minutes, tidying up. Leave things alone during this time.
