Laurie,
What Clarence says is correct, but I don't think that he said enough.
If you use fdisk to reformat your HD, you will lose files on the drive. I
would suggest a program like Partition Magic that will resize partitions on
the fly and not require the partition be reformatted.
I have a 540 MB HD on this computer and an 800 +/- MB HD on another. Both
are partitioned into a primary DOS partition (C:) and an extended DOS
partition with logical drives D: thru K:. The maximum size partition is
about 120 MB and the smallest is 20 MB.
A word of caution. If you create a partition smaller than 16 MB, the cluster
size is 4 KB. Larger than 16 MB and smaller than 125 MB, the cluster size is
2 KB.
I got a program from PC Magazine years ago called CHKDRIVE, which checks the
efficiency of partitions as sized and the efficiency if they were partitioned
with other cluster sizes. (Partition Magic does the same thing.) Most of my
drives are in the 96 percent efficient area, however, if the partitions had
16 KB clusters, they would be in the 60 percent efficient range. That is
almost half of your partition that has nothing in it and cannot be used!
Hope this helps.
