Silverlining Lite v2.1.1 Drive Management Software Online Documentation
Sept. 12, 1997
Silverlining Lite is a program which provides essential Macintosh drive management functions in a convenient control panel. Use Silverlining Lite to quickly mount and unmount volumes, change polling preferences, format drives, and erase volumes.
Silverlining Lite makes it easy to work with removable cartridge drives by automatically mounting an icon on the desktop when a cartridge is inserted. Without Silverlining Lite, you would need to use SCSI Probe, Silverlining, or some other similar program to manually mount an icon after each cartridge is inserted.
Silverlining Lite v2.1.1 improvements
• Increases data transfer rates for drives mounted on internal "fast" busses up to 10 MB/sec. or higher by utilizing high speed synchronous bus data transfers.
• Supports installation of Silverlining driver on drives with other drivers, including Apple, FWB, APS and Anubis drivers. Silverlining Lite always replaces other drivers.
• Improved performance when ejecting cartridges. Silverlining Lite no longer waits for the mechanism to finish the cartridge eject after issuing an eject command.
• Driver does a more thorough job of error detection and retry. This avoids disk errors associated with Jaz drives and others.
• Driver now detects if a disk is removed from the bus with a volume mounted and asks the user to re-connect the device to prevent loss of data.
• Support of System 8.x. Silverlining Lite includes support of System 8 appearances in windows and dialog boxes.
• Silverlining Lite now features full support of individual volume passwords and drive master passwords. You can prevent users from mounting a volume or modifying a volume without the correct password. System administrators can use a drive master password as a backup in case users lose their individual passwords.
NOTE: The data stored in the Start Block has been changed slightly .
Versions of Silverlining prior to 5.8 will report "Start block invalid" on any drive initialized with Silverlining 5.8 or Lite v2.1 or later. This is normal and does not constitute a problem.
Silverlining Lite compatibility
Silverlining Lite is fully compatible with all Macintosh models (including PowerBooks, AVs and PowerPCs), Macintosh system software versions 6.x, 7.x, and 8.x); SCSI Manager 4.3 (including Macintoshes that support multiple SCSI buses), Macintosh IDE drives, and Speed2 Drives. This includes IDE and SCSI hard drives, magneto-optical (MO) drives, Jaz, Zip, and MCD. Silverlining supports the Terabyte file system (64 bit addressing scheme) which was introduced in System 7.5.2. Also supported are 512, 1024, 2048, and 4096 byte per sector drives.
Installing Silverlining Lite
1. Start up from your primary drive.
2. (Optional) Remove all copies of Silver Volumes and Silver Control from the System Folder of your startup drive before installing Silverlining Lite.
Silverlining Lite replaces Silver Volumes and Silver Control so these two files are no longer needed.
3. Copy the Silverlining Lite icon from the Silverlining Starter Kit folder or floppy disk to the System Folder icon of the startup drive.
For System 7 users, the Silverlining Lite icon will be placed in the Controls Panel folder automatically.
4. Restart the Macintosh
Opening Silverlining Lite
1. Choose Silverlining Lite from the Control Panels menu in the Apple menu.
You can also open the Silverlining Lite window by double-clicking the Silverlining Lite icon.
Note: Once Silverlining Lite is installed, you may see a dialog box when you insert a new or uninitialized cartridge into your drive. Clicking on Initialize will automatically format and initialize the new cartridge into one Macintosh volume without running Silverlining Lite.

Bytes/Sector: The number of bytes in each sector.
Cylinders (tracks): The pair of tracks on opposite sides of the disk platter. If a hard disk contains multiple platters, a cylinder includes the pair of tracks directly above and below each other on each disk platter. On a hard disk containing four platters, each cylinder contains eight tracks.
Heads: The total number of read/write heads on the drive.
Sectors: The average number of sectors on each track.
Interleave: The number of revolutions required to read every sector on a track. Most hard drives use a 1:1 interleave factor.
Partition Number: Partitions are assigned numbers by Silverlining Lite. The first partition is assigned number 0, the second partition is assigned number 1, and so on.
Note about “Invisible” partitions: A drive normally contains a handful of partitions that are used to store drivers, directory files, and free space. They are called “invisible” partitions because they don’t appear as mounted volumes on the desktop. Examples are “Apple (partition_map),” “Macintosh_SL (Driver),” and “Extra(Free).”
Partition Name: The name that identifies the volume in Silverlining and on the desktop (for mountable partitions).
Partition Type: Identifies the structure and purpose of the partition. These descriptors are designated at the time Silverlining creates the partition. See “Partitioning the Easy Way” in Chapter 2 for details. For Macintosh HFS partitions, the partition type is “Apple_HFS.”
First Block: Identifies the address of the first block on the selected partition.
Block Count: The total number of blocks on the partition.

Total Files: The total number of files on the volume.
Fragmented Files: The total number of fragmented files on the volume.
Setting up a Drive or Volume
Silverlining Lite can format drives and erase volumes.
Formatting is a time-consuming process and should be performed only when absolutely necessary. Most drives come pre-formatted and should not require formatting for the life of the drive. Considering reformatting when Silverlining Lite indicates that it is unable to access data on the drive because the driver and directory files cannot be recognized or have been corrupted beyond repair. Formatting destroys the data on ALL volumes of the drive. Silverlining Lite will format only those drives that support 512, 1024, 2048, and 4096-byte sectors.
By default, Silverlining Lite creates a single large partition when you format a drive. You can use the “Custom” feature in Silverlining Lite to specify the number and size of partitions during formatting. If you resize or add partitions with Silverlining Lite, all existing data on the drive is lost. To resize or add partitions without losing data, use Silverlining Full Version.
Erasing a volume removes the directory files on the volume. This process usually takes less than a minute, even for larger volumes. You can erase one volume of a drive without affecting the data on other volumes of the same drive.
Warning! Be sure to back up the data on all volumes before formatting a drive or initializing a volume. Formatting erases all of the data on all volumes of the drive; the information is gone forever and recovery programs cannot bring it back. Erasing removes the directory files on a volume, making it difficult to locate file data even with a data recovery program.

Volume Security and Passwords
Silverlining Lite offers two levels of security: you can prevent users from mounting a volume without the correct password, or you can prevent users from modifying a volume without the correct password. For example, to restrict access for a particular volume to a single user, assign a Mounting password and give the password the user. All other users will not be able to view or modify the volume. To make a volume available for read-only, assign a Lock password. All users will be able to view the volume but won’t be able to unlock the volume and modify its contents without the password.
Once you’ve a set passwords for a volume, users will be automatically prompted to enter passwords the next time they attempt to mount or unlock the volume. Note that any Silverlining Lite user can still reformat the drive without a password.
Warning: Memorize your password! If you forget the password, you must initialize the entire drive and you will lose everything. Consider setting a Master Password and writing it down in a secret place in case you (or a user) forget the volume password. Passwords are case-sensitive: ROME and RoMe are different passwords.
To assign a password to a volume
1. Open Silverlining Lite
2. Click a volume entry
3. Click Options.
4. Click Password to assign a password.
The password you assign will apply to both mounting and unlocking this volume.
 
5. Type in the password and click OK
Silverlining does not allow the following keys from the 10-key Key Pad to be used in volume passwords:= / + - . *
Silverlining ignores the Option, Control and Command keys when typing passwords.
6. Retype the password and click OK.
Now that you assigned a password to the volume, the volume is not secure until you lock-protect or mount-protect the volume as described below.
To mount-protect a volume
1. Password-protect the volume.
2. Select Password to Mount.
This prevents users from mounting the volume without the correct password. Users will be automatically prompted to enter passwords the next time they attempt to mount the volume with Silverlining. If the Mount at Startup option is selected, users will be automatically prompted to enter passwords at startup time.
 
Note: If you later return to this dialog box and deselect the Password to Mount setting, you will be prompted to enter the correct password.
3. Click OK to return to the main window.
To lock-protect a volume
1. Password protect the volume.
2. Choose Password to Unlock.
This prevents users from unlocking the volume without the correct password. Users will be automatically prompted to enter passwords the next time they attempt to unlock the volume in Silverlining or at the Finder.
 
Note: If you later return to this dialog box and deselect the Password to Unlock setting, you will be prompted to enter the correct password.
3. Click OK to return to the main window.
Master Passwords
Silverlining Lite offers two types of passwords: individual volume passwords and a single Master Password for all volumes on a drive. Once a Master Password is set, it can be used in place of any volume password on the selected drive. System administrators find this feature useful as a backup in case a user forgets his or her password.
To set a Master Password for all volumes on a drive
1. Open Silverlining Lite.
2. Click a volume entry for any volume on the desired drive.
3. Click Options.
