No recovery software displays my deleted files!



A folder of important DVD images (.iso and .nrg files) has disappeared from my hard disk. I am positive I have not written any data to that drive since then. So, there is no question of these deleted files being overwritten. I have tried many high and mighty recovery softwares (almost all of them), but they don’t show these files, even in their advanced scans, as if they never existed. But they show all the other deleted files, even those which I deleted ages ago, and which are totally unrecoverable. Please, please help me. Can anybody guide me about what the problem could be? I 'll be very gratefull.


This is probably because the files are too large? They are generally too large for the trashcan, so it might very well be possible that these are also too large for any recovery program…
