WOW, for some reason when i deleted both of them they stayed as unallocated seperately, but now i did it again and they merged, must messed some little thing up the first time i tried :/
o well thanx for the help
[concern] if i use dban, which i have looked at before but was unsure about it, can i select what disk to erase when i pop it in or does it just wipe any drive plugged in to the comp?
