I have a samsung hd SV3064D 30 gbs thats been giving me trouble lately i can't format it in windows and when i format it in Dos it takes a lot longer than usual and ends up not working when i try to install a OS on it it has corrupted files. im pretty sure its the clusters but i cant find a solution that works. I ve tried scandisk and it wont work even outside of windows on dos. ive tried looking for samsung progs and that didnt work. i tried looking for a low level format prog and couldnt find one. some one HELP PLZ!!!
