Last Modified: 2012-05-06
I am using Windows 7, and I have a 1 TB drive that was formated as FAT32 and is about 80% full. Is there away to change it to an NTFS drive without having to remove and reformat it?

I would try convert driver_letter: /fs:ntfs

this works for most windows products, should be the same for windows 7 try doing convert /? and verify the syntax

This should convert on the fly without a reboot.

Should be the same as in XP or Vista:

To convert drive C:  

convert c: /fs:ntfs

It will probably ask you to reboot since drive is in use. Change c to whatever drive you are trying to convert.

paul is correct.  ozirisno1, I believe misread the question - you have NO REASON to run CONVERT C: /FS:NTFS since you are asking about an EXTERNAL drive.

I'm not sure that I understand you. Are you saying that I would not do "convert /fs:ntfs" ? if so what would I do to convert it?

No, I'm saying you should not run

Note: the C: part.  Is your external drive the C: drive?

(Windows 7, I'm 95% certain) cannot be installed on a fat partition since it makes use of junctions in the file system.

yes it's an external drive,a usb drive. But are you saying that I cannot covert it or is there a different method I am suppose to use? If it is a different method can you specify?
