Thanks for the heads-up. I thought of the same thing, but I wanted to consult the ppl with more experience than myself.

Btw, the VB project I mentioned in post #33 seems to do exactly that, at least to me. From the brief look I had, I figured that it was retrieving the locations of data on the hard drive via some API calls and then writing bytes on that same location. But, as I said, I am not very familiar with classic VB and APIs, so it would be better if someone more experienced cast a glance at the code.
