Thank you so much for your big efforts, just downloaded and have an overview, very good job and manuals, will go into details asap! We have been using the DFL tools for over 4 years with good success, keep it up. Btw, when can we expect other new manuals for other hdd brands, lol?
Hello friend, thank you for your feedback and we are working on other new manuals too and we will release asap once completed. We have completed many new software functions and will release new software soon too. Please keep an eye on our news section.
