|Missing Disk Space! (The Great Cluster
I have a 1 gigabyte hard drive with 123 megabytes showing as free space. When I go into Windows Explorer and highlight everything on the drive and check the properties, the used space is shown as 643MB, which means that I am missing about 226MB of drive space that I sorely need. Am I reading the information right?
95, with the exception of the "B"
release, uses the FAT16
file system. Space on the hard drive is divided up into
storage allocation units, or "clusters." Each
file on the disk takes up one or more of these clusters.
Since most files do not fit evenly into a certain number
of clusters, there is usually some slack. For example, a
20,428-byte file stored on a disk using an 8KB (8192
byte) cluster size actually occupies 3 clusters (24,576
bytes) -- 4148 bytes are "wasted." In other
words, the total amount of space used by your
files is less than the amount of disk space occupied
by those files.
Subdivide large drives into two or more smaller
partitions. This reduces cluster size and increases
storage efficiency. Unfortunately, this also means that
you will lose the entire contents of your disk in the
process. If you don't wish to reload the operating system
and all your applications and files, you will need to buy
a third-party utility such as PartitionMagic, which can create or re-size partitions
on the fly.
