The drive you have drawn out is an ata,which sort of works backwards
from the 'normal' drive on that on you pull all of the jumpers to make
it a slave,and move it depending on whether there is another drive
present.on a 'normal' drive,you'll still have the same set of six
pins,but you'd want to move the jumper to the center set
I looked through my bookmarks,and came up with some hard
drive/jumpersetting places you may want to check out.

,or

second 'd' was uppersase or not on that one.
