ATA-100 Cable?

Ok, this may be a dumb question, but is there actually a difference between the cables you use to connect HDs to Motherboards? How can I tell what kind of cable I have?

------------------
Athlon T-Bird 900 Mhz
MSI K7T-Pro 2A
128 MB PC-133
64 MB PC-100 (2x)
20 GB Maxtor ATA 33/7200
6.4 GB Maxtor ATA 33/5400
Hercules MX II - 32 MB
HP CD-RW
Pioneer DVD (105-S)
Monster Sound MX300
19" KDS Flat Monitor

Physically, there is a difference between ATA33 and ATA66/100 cables. ATA33 cables are 40-pin, ATA66/100 are 80-pin. You could count the pins I guess, but if you've seen the two side by side it's pretty easy to tell which is which. 40-pin cables have relatively thick ridges, 80-pin cables have thinner ridges.
