I have 4 of my hard drives in an extended partition using windows 7. What happens if one of the drives go bad? will I lose all of my data? Can I "un-extend" partition them without losing data? What if I take the 4 drives out and put them into another computer, what will happen? and finally what are the pros/cons between RAID1, RAID5 and the extended partition? Lots of questions but hopefully someone has a straight answer. Thank You.
