Setup Requires Unusually Large Amount of Disk Space (152629)
The information in this article applies to:
This article was previously published under Q152629 SYMPTOMS
Installing Windows 95 on a compressed hard disk may require an unusually
large amount of disk space. Instead of the 40-90 MB that Setup usually
requires, it may require up to 256 MB of free space.
CAUSE
This behavior can occur if the compressed hard disk has an estimated
compression ratio (ECR) that is much higher than the actual compression
ratio (ACR). Setup calculates the free disk space manually and converts
its result to match the amount needed given the current ECR.
RESOLUTION
To resolve this issue, use either or both of the following methods:
- Free the amount of hard disk space Setup requests.
- Change the ECR to match the ACR. For MS-DOS 6.0 and 6.2, use
MS-DOS DoubleSpace (Dblspace.exe). For MS-DOS 6.22, use MS-DOS
DriveSpace (Drvspace.exe).
MORE INFORMATION
Windows 95 Setup does not use the free space information provided by
DoubleSpace or DriveSpace. Instead, it determines the actual amount of
free space on the hard disk and then applies a calculated compression
ratio to the Windows 95 files. The amount of hard disk space requested is
the amount actually required adjusted to match the ECR.
