new hard drive and partitions.

Hi all. I have installed another hard drive to my system; it is on the
secondary IDE as a slave- because of the ribbon cable positions. Anyway,
both my main HD and this new hard drive have 3 partitions each; 1 primary
partition and an extended with two logical devices on each - total of six.
Problem is, windows now makes the primary partition of the second drive my D
drive. In other words, before the new drive i had C:, D: and E:.
I now have C D E F G H, BUT the D drive is from the secondary drive, while E
and F are from my primary drive (what used to be labeled D and E). You can
see that the problem is, anything I had installed on my original D and E
partitions are now a different path. IS there a way to correct this without
re-installing the programs or reassigning the paths? Ideally, I would like
to keep C D E for my primary hard drive and the other letters for my
secondary.
Thanks a million in advance.
