I'm not sure if this will apply in 98 but maybe someone can give it a try. From 95B on, you can force the size of the clusters with the following switch; /z:1 will give you 512K clusters (no matter how big the drive) /z:2 will give you 1020K clusters /z:4 will give you 2048K clusters You get the idea, multiply by 512.
