Hi and thank you and appreciate for lightening responce I did an all scan with avg antiv and the system is clean i suppose and there is something else,in safe mode the w98 partition is c: winxp part e: and the 320 gb hd w/o op system has d: drive letter. In win xp the drive letters are c:win98---- d: winxp----- e:empty fat32 And something another the partitioning and formatting of empty 320 gig hd it became with a boot cd that gave to me from a friend, from dos before the operating system. And something else ,when i turn to turn off from win xp ,explorer takes a little time about 15 sec to close.
