Hi, I know the new name of SCANDISK in 98 is CHKDSK in XP. But with SCANDISK in 98 , we could also see the bad sectors , which is unavailable in XP. Actually the problem is my kingston pen drive has got bad sectors( I know it coz the data gets corrupted quite often and only reformat helps), its in 5 year warranty but to get it replaced I need to show my dealer that it has bad sectors coz earlier when I took my corrupted pen drive to him , he formatted it and said its working fine. Now I wanna show him the bad sectors , I m using XP SP2 , how can I do that ????
