if your removing the secondary drive from one computer and inserting it into another you should be fine. you won't lose any of the information off of it nor will it have to be partitioned. The biggest thing you will have to make sure ofis to see if the drive is set as master or slave and the position of what cjhain your puttingit on. if you are putting it on the primary IDE chain in the second slot, it would have to be set to slave. that also holds true if you are putting it on the seconadry slot on the secondary IDE chain. though if you are placing it on the primary slot of the secondary IDE chain it would have to be set to primary. Don't worry to much about changing it over, unless the information is already lost, it should be perfectly fine.

just always remember to touch the metal part of the case before touching anything inside the computer
