Once I restart my computer-Suddently The partition D was invisible. I gues it's because of bad sektors. There are many softs for XP to solve this like active partition recovery, partition disk doctor and so on, but I couldn't find any soft for win 7! Do I need to instal WINDOWS XP as secound? And how to do it if I have only 1 partition left, where is WIN7 already? Maybe there's any soft wich suport win7? Has anybody experience with this?
