Q11: How can I get 32-bit disk access in Windows 3.1x?
A: Run the SETUP .EXE program located on your EZ-Drive
disk to install the 32-bit disk access driver. See Enabling 32-bit
Disk Access in Windows 3.1x on page 27.
Q12: Should I create more than one partition on my hard drive?
A: If your hard drive is 2.5 GB or larger, you must create at
least two partitions for DOS, Windows 3.x, Windows 95, or
any operating system that uses FAT 16.
EZ-Drive and Fdisk utilities allow you to divide the hard drive
into multiple partitions that function as separate drives.
In DOS, every file that is stored gets at least one allocation unit
(called a "cluster"), regardless of the file size. The size of the cluster
increases with the size of the partition. For example, if you have a
1024 MB partition, the cluster size is 32 KB. This means that even
a 62-byte batch file is going to consume 32 KB of storage space. A
typical mix of application and data files can include thousands of
files. If each file contains a few kilobytes of wasted space, this can
add up to several megabytes of wasted space.
To reduce cluster size you must reduce the partition size. The
following table lists the breakdown for DOS 5.0 and above.
