I want to write a program to make a image file of a disk, but I do not know what's the basal knowledge I have to learn...
Is there any criterion and Standardization I should to learn?
Thanks...

Do you want a RAW image or just the files with directory structure? If the latter one, then you can just load & pack all the files into some kind of an archive.
the latter, just like the .img, .dat, .iso files...
how to actualize it? Do I need know the .img, .iso file structures?

On NT systems, simply look up the "special" filenames you can open with CreateFile, namely \\.\x: and \\.\PHYSICALDRIVEx . You'll need to get disk/partition size somewhere, though.
The format you choose to backup to will be your own headache.
