i can't get it to format the drive.. i says it cannot be locked, and when i try and lock it, it won't let me... its like i'm screwed.. so i get in dos, type lock, and it ask's if i wanna do it, i say yes, then it goes blue, and says insert disk into drive a, and i did, then hit a key, then it says insert a disk into drive b, and i have no drive b.
