/RATIO Switch Not Valid with DRVSPACE /CREATE Command (125709)
The information in this article applies to:
This article was previously published under Q125709 SYMPTOMS
When you use the /RATIO switch to set the estimated compression ratio
(ECR) when you are creating a new, empty compressed drive with the
DRVSPACE /CREATE command, the ratio value that you specify is ignored.
The ECR for the new compressed drive defaults to 2.0:1.
CAUSE
The /RATIO switch is not valid when used with the DRVSPACE /CREATE command.
WORKAROUND
Set the ECR for the new compressed drive after the drive has been created.
To set the ECR for the drive, use the DRVSPACE /RATIO command, or run
DriveSpace from inside Windows 95.
The syntax for the DRVSPACE /RATIO command is
DRVSPACE /RATIO=n.n <drive>
where n.n is the new ratio you want to use and <drive> is the drive letter
of the compressed drive.
To change the ECR from inside Windows 95 DriveSpace, perform the following
steps:
- Click the compressed drive whose ratio you want to change
- On the Advanced menu, click Change Ratio
- Drag the slider to the desired value.
STATUS
Microsoft has confirmed this to be a problem in Windows 95. We are
researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
When you create or resize a compressed drive, DriveSpace defaults to a
ratio of 2.0:1. The default ECR is always used by DriveSpace when you use
the DRVSPACE /CREATE command.
REFERENCES
For a complete description of the command-line parameters for DriveSpace,
see the Microsoft Windows 95 "Resource Kit," Appendix A, "Command-Line
Command Summary," or run the MS-DOS 6.22 Help by typing
from the DOS directory at an MS-DOS prompt.
