Try and space any hard drives as far away from each other as possible in the case as well. This is not the place for discussing all of those problems, but be warned that getting your computer and operating system to recognize all the drive you bought may end up being its own unpleasant exercise. Along with the general problems high capacity drives cause with DOS, there s also the issue of cluster size. DOS organizes your hard drive into clusters, which consists of a number of sectors on the drive. How many depends on how large the formatted capacity of your drive is.
Larger partitions use larger clusters.
This impacts you in two ways. First, more space is wasted if your partition size is larger and you have many small files. Second, the overall access speed to small files becomes greater as the cluster size increases. Large cluster sizes can cause systems with marginal performance to have more problems keeping up with the speed of CD-R writing.
