Can I read a disk's raw data, like in a hex editor?

[Karl Becker]

I have a formatted FAT32 or NTFS (I can change the file format) MMC  
card from which I would like to read data.  However, the data stored  
to the card is not written into a tradition file, but rather directly  
to the disk and not in a file of any sort.

Is there anyway to read the raw contents of a disk with Revolution?

Thanks,
Karl
