ok i have two Hard drives, a WD 40 gig and a WD 120 gig. 40 is master 120 is slave. i have had this set up for about a year and a half. but yesterday my 120 gig seems to be deleted kind of. windows xp sees the F drive (120 gig) but i can not access it anymore. when i do try i get a popup saying this drive is not formatted do you want to format? I went to my computer>manage and it sayas that it is healthy. so here are my questions. what happened? what can i do to avoid this again? if i format it wont that delete any information on it? is it dead? one more thing how do i get windows xp to actually recognize it as 120 gig HD instead of 111 gig HD?
