2nd HD install question cable orientation

This is probably a dumb question but do hard drives have a "correct side up"?
i.e., does it make any difference whether the green circuit board side or the
metal side is upright in the computer? The reason I ask is I'm installing a
2nd HD in my 8600, and I noticed when I unplugged the cable from the first one
that the drive is right side up but that the cable went up and under (upside
down) in order to accomodate the notch on the connector. Therefore I couldn't
use the pull-tab assist to disconnect it (it was underneath), so I just
disconnected it with my fingers, no problem. However, when I install the
second drive, if I connect the 1st exactly like it was, the connector for the
2nd drive is on the wrong side of the cable and can't be plugged in. And if I
just twist the cable to get both connectors on the same side, then the notches
in the connectors are in the wrong place. I dug out a non-Dell cable I had and
sure enough, the Dell connectors are upside down compared to the non-Dell
cable. The only way I can figure out how to continue using the Dell cable is
to put both drives "upside down". I guess I could use the other cable I had,
but it doesn't have the pull-tabs which I like for easier disconnection. For
those of you who have installed a 2nd HD, how did you orient your drives and
route your Dell cable to get the connector notches to line up? Is this weird,
or am I? grin
