                              DRVSPACE /RATIO
 
Changes the estimated compression ratio of the selected drive. DriveSpace
uses this ratio to estimate how much free space the drive contains. You
might want to change the estimated compression ratio if you plan to store
new files with a compression ratio that differs greatly from the current
ratio.
 
Syntax
 
    DRVSPACE /RATIO[=r.r] [drive: | /ALL]
 
Parameter
 
drive:
    Specifies the drive for which you want to change the estimated
    compression ratio.
 
    You can include either a drive letter or the /ALL switch, but not both.
    If you specify neither the drive nor the /ALL switch, DriveSpace changes
    the estimated compression ratio for the current drive.
 
Switch
 
/RATIO=r.r
    Changes the estimated compression ratio of the specified drive(s). To
    change the ratio to a specific number, specify the ratio you want. You
    can specify a ratio from 1.0 to 16.0. If you don't specify a ratio,
    DriveSpace sets the drive's estimated compression ratio to the average
    actual compression ratio for all the files currently on the drive. This
    switch can be abbreviated as /RA.
 
/ALL
    Specifies that you want to change the ratio of all currently mounted
    compressed drives. (If you use this switch, you cannot also specify a
    value for the drive parameter.)
