Some people have had success with this program in recovering cards, others feel that it is the best way to properly format your SD cards, and gain usable space from it etc. so, what are peoples results with it? who has gained space on their card by using it, or noticed a perceived performance improvement? I never bothered to make any comparisons with it, and have forgotten about it the last few times I've formatted cards. But, will probably try it out on my 1 gig and 2 gig Kingston (japan) later if no-one else posts their own results.
