Custom DR Software

I would like to write my own simple Data Recovery program. I have heard everything from using AT Commands, to programming in C+ (Which I don't know). Does anyone have any advice on where to start? I would like to get something going for my own personal use.

Thanks a ton!

Hi,

For dealing with IO ports assembly is the best

I write the very low level code in assembly and the more complex things in C.
