I have just imaged a FAT32 disk drive on a NTFS disk drive. I'm aware I could have imaged on a FAT32 HDD and convert it later, but I figured it out too late and I'm trying to save processing time (I have other stuff to do on both of my computers).

The disk image is a .dig, made with DrvImagerXP.

So my question is, is there any tool out there that converts disk images?

What sort of disk images? Without mentioning details of the image format and program used to create it, there's insufficient information to answer this question. – Karan Mar 11 '13 at 3:11
I didn't think it'd be needed since I thought an image is basically a "one and zero" copy of the disk. But I didn't take into account the stupidity of headers that could have been attached with the file, well seen sir. – Dominic Grenier Mar 11 '13 at 3:58

Is it an ISO? Find a tool to mount it, then use the built-in convert utility.

No, it's a .dig so I decided to split my file into parts with HJSplit and partition a disk where i'll put the parts and convert them one by one. I'm going to accept your answer though if you specify a mounting tool that has a built-in convert utility (since the one I have doesn't seem to have any) so I can try it and check this as accepted :) – Dominic Grenier Mar 11 '13 at 1:53
How do you create an ISO with a FAT32 file system? Even if you can, will convert be able to modify the file system inside a mounted ISO? Which tool mounts ISOs in a writeable manner? Have you ever tried something like this? – Karan Mar 11 '13 at 3:12

Here's some info about the topic that may be pertinent. It says to

"Now go to Start Menu >Run >cmd (Command Prompt) and Type the following command: convert Y: /fs:ntfs (Where “Y” is your USB drive letter). This will convert the USB Flash drive from a fat32 to a NTFS file system"

Here is the Link

I do not have any removable devices that are large enough for my image and fat32 doesn't take files over 4gigs, my image is 19 gigs. – Dominic Grenier Mar 11 '13 at 1:54
