Backing Up To Hard Drive (Not Disc) Question

[Guru Imakuni]

I have a DVD drive, just not a burner. I used a program, called Alcohol 120% to make an image file, but it was backed up in their format. It ended up being a .mdf and a .mds file. I'll have to try another program, like Clone CD to make an .iso but from what I hear Clone CD can't do DVDs so I may end up with nothing, that's my problem.
