Hey folks was wondering if i had a pc with windows 7 installed could i add in two other drives i have? and if so would they need to be formated?. they are already formatted to windows vista but am having to much trouble with that but dnt want to lose all my stuff on them the vista os is still on one of them but i have partitioned both of them

If you are just wanting to add them to a system as data drives then no, you don't need to format them.

True.

NOTE: If they are IDE/PATA drives,be sure to set the jumpers correctly in order to tell your system which one is the MASTER drive and which ones are the slave ones!!!
