Disabling a secondary HD

[zelgadis123]

I have two harddrive connected. One is a ATA 133 16mb, the other a hand me down ATA 100 2mb. I heard if you connect them together they become ata 100 speed right? I was wondering, when I am trying to be annal about performance, if I disabled the ATA 100 by going to system under control panal, would the computer revert back to ata133? I would like to keep the ata 100 2mb for storage. Is it even safe to disable harddrive that way? Just a very curious question

dont worry hard drives dont use the whole ata133 or ata100 anyways the usually avarage transfers are in the 40mbs and 50mbs range.
