DISKINFO v1.0 disk information utility (C) Copyright 1995 Scott Slater


DISKINFO is a simple utility that shows information about any disk on
your system. The story behind this utility is a long one so I won't go
into boring details on that. But I will tell you that you will be shocked
by the information that I am about to give you. The filing system used by
DOS and Windows 95, as well as a few other operating systems known as the
FAT filing system does really poorly at managing disk space. Your disk is
made up of many small units known as "sectors" and these units are grouped
together into bigger units known as "clusters". The "cluster" is the
smallest place where any file can be stored. So lets say that your cluster
size is 8,192 bytes long. Now you store a 1 byte file in that space. That
file can be the only file occupying that space so it will take 8,192 bytes
away from your total free space, therefore the disk is wasting 8,191 bytes
by allocating more than you need. The same is true for bigger files.
Let's say that you have a file that is 8,193 bytes long (1 byte bigger than
the cluster size). Now to store that file your disk needs 2 clusters.
Totaling 16,384 bytes assuming that your allocation unit size is 8,192.
Since no 2 files can occupy the same cluster at the same time, then you can
see why so much space would be wasted on a system with many files. If you
only had one large file then you would only lose a few bytes (less
than 8,192). But since that is not the case your hard drive is throwing
away tons of good usable space due to over allocation. The problem is that
there isn't much that you can do about this except switch to a new type of
filing system like OS/2's HPFS. HPFS only uses 512 bytes per cluster.
Another thing to keep in mind is that the difference in cluster size
depends mainly on the manufacture of the drive itself. So now you are
saying "hmmmm, I wonder how much space my drive is wasting!" Well when
you run DISKINFO, you will know.... and probably be ticked!

How to USE:

To find out the information for any given disk run DISKINFO from that
disk. The best way to run this utility is to place it somewhere in your
path (i.e. your DOS directory) and then switch to the drive you want info
for and type in DISKINFO at the DOS prompt. DISKINFO does not accept
commandline parameters.
