Macintosh Manager: RAM Disks and Multiple Users Interaction

Symptom

Mac OS 9.x

RAM disks disappear from the desktop when a user logs out of the Macintosh Manager and Multiple User environments.

Mac OS 8.6 and earlier

An alert box appears with this message, and you have to restart the computer:

"You do not have access privileges to use removable media volumes."

Solution

If the Macintosh Manager administrator wishes to grant access to RAM disks on client computers, the following settings should be enabled.

1. In the Macintosh Manager Admin Utility, enable "Read/Write access to Removable Media (except CDs)" under the Workgroups Tab:Privileges Tab:Privileges box:Removable Media (except CDs)

2. In Multiple Users, each user must be granted access to removable media separately. This setting is located in the Details section of each user account under the Privileges Tab: Other Removable Media.

3. In order to avoid the above symptoms an administrator must grant the Removable Media privilege to all workgroups (Macintosh Manager) or users (Multiple Users) who could potentially log in to a client using a RAM disk.

Note: Each client computer maintains the contents of the RAM disk locally, not the Macintosh Manager server. All users will have Read/Write access to the RAM disk if they are granted access to removable media. RAM disk contents are lost in the event of a loss of power or other improper shutdown of the computer.
