I have a computer in with an 80gb hard drive, a 250mbzip drive and a dvd/cdrw drive. It's running winxp pro w/ sp1a. the hard drive is drive E the Zip is drive C and the cdrw is the D.

Now the hard drive is the primary master
Currently no primary slave ( will be another 80gb hard drive )
the cdrw is the secondary master
the zip drive is the secondary slave

Why are the drives labeled that way and how can you change them.

I disconnected the zip and the hard drive is still E.

Is this another microsoft "confuse the user" feature or what?
