zip and hdd on primary channel

If I put my zip drive (real old, only 100 MB) and my WD HDD (7200 rpm) on a primary channel will it slow down my harddrive when i'm not using the zip drive?

No. Use an ATA133 cable and you should be fine.

ok, well since i added the zip drive my the red light that says my harddrive is spinning is always on. how do i fix this?

haven't seen this problem w/ hdd, but a common occurance with floppies. Double check that the cable is put on correctly, not upside down. I've seen this done with FD numerous times (done it myself a couple). Also check that the hard drive is the First in channel, as this will occasionally cause some minor issues if it's 2nd in line.

Your zip will slow down your HD, put them on seperate channels. As a matter of fact, don't put your CD Roms with your HD either.
