Pre-System 7.5 Macintoshes support volume sizes up to 2GB
System 7.5 can handle volumes up to 4GB
You can raise the maximum reported size for SFM volumes to 4GB
by creating the SFM volume, then editing the registry entry:
HKEY_LOCAL_MACHINES\System\CurrentControlSet\Services
\MacFile\Parameters\Volumes\<VolumeName>
Properties=xxxxx
by adding 262144 (0x00040000) to the number xxxxx.
Stop and restart Macfile to make this change take effect on the SFM volume.
In Windows NT 3.51 you can change this value globally for all volumes. To do this, add bit 0x10 to the following section of the registry and every
volume will be 4GB enabled:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
\Services\MacFile\Parameters
ServerOptions: REG_DWORD: xxxx
