Converting drive from FAT32 to NTFS

Hi! I recently installed Windows XP, but never converted my drive from FAT32 to NTFS. I now want to do this, but don’t want to lose any of my data.

When I tried to do the conversion (the sectors are aligned properly and the disk is defragmented), I went to the command prompt and typed “VOL C:” – got the name of the drive and the volume serial #. When I typed “convert c: /fs:ntfs” I got the following error:

‘convert’ is not recognized as an internal or external command, operable program or batch file.

I searched my C drive for “convert” and it showed up as an .exe file in c:\windows\system32. I tried clicking on that, but it just brought up the Command Prompt window for a second and disappeared.

Help!!
