more than 2years ago i run FDISR (raxco) on my laptop but it didn't work, next week i will received my new HDD and i planning to run FDISR again. I'm confused right now because there's a FDISR from leapfrog (?) and there's FDISR from Horizon Data....i would appreciate if somebody will tell me what's the difference between two FDISR? Also, i downloaded FDISR from leapfrog can i still buy a license from them or just go to Horizon Data? thank you.
