The cable should have it printed on it and use the utility that came with the hd

i think u can change the speed in device manager if ur harddrive supports ATA 100

You can use Sisoft Sandra to verify what your current UDMA setting is, and what the maximum UDMA setting is that your hard drive supports, if you are not sure what they are.

By the use of one 80 pin cable the drive will operate at the max speed automatically ..
All the modern drives do that ..

And there is no any ATA 66 and ATA 100 cables , there is only 80 pin cables (double shielded) or 40 pin cables (plain IDE) .
